Adding Color and Hover Options to VisNetwork Igrap

I have been having trouble with this. I can only get one or the other but not both options in one graph. Below is the code and I received a lot of help from @lukeA to get me to this point.

I have the following graph in which I can get the cluster colors into the visNetwork Igraph:

library(igraph)
library(visNetwork)
B = matrix( 
c(1, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 47, 3, 0, 3, 0, 1, 10, 13, 5,
0, 3, 19, 0, 1, 0, 1, 7, 3, 1,
0, 0, 0, 3, 0, 0, 0, 0, 0, 0,
0, 3, 1, 0, 32, 0, 0, 3, 2, 1,
0, 0, 0, 0, 0, 2, 0, 0, 0, 0,
0, 1, 1, 0, 0, 0, 2, 1, 1, 0,
0, 10, 7, 0, 3, 0, 1, 90, 12, 4, 
0, 13, 3, 0, 2, 0, 1, 12, 52, 4, 
0, 5, 1, 0, 1, 0, 0, 4, 4, 18), 
nrow=10, 
ncol=10)
colnames(B) <- c("A", "B", "C", "D", "E", "F", "G", "H", "I", "J")
rownames(B) <- c("A", "B", "C", "D", "E", "F", "G", "H", "I", "J")

g96e = t(B) %*% B

i96e = graph.adjacency(g96e, mode = "undirected", weighted = TRUE, diag=FALSE)

V(i96e)$label = V(i96e)$name
V(i96e)$label.color = rgb(0,0,.2,.8)
V(i96e)$label.cex = .1
V(i96e)$size = 2
V(i96e)$color = rgb(0,0,1,.5)
V(i96e)$frame.color = V(i96e)$color
fc<-fastgreedy.community(i96e, merges=TRUE, modularity=TRUE,
                     membership=TRUE, weights=E(i96e)$weight)
colors <- rainbow(max(membership(fc)))

col = c("#80FF00FF", "#FF0000FF", "#FF0000FF", "#00FFFFFF",
    "#FF0000FF", "#8000FFFF", "#FF0000FF", "#FF0000FF",
    "#FF0000FF", "#FF0000FF")
i96e <- set.vertex.attribute(i96e, name = "group",value = col)
i96e = graph.adjacency(g96e, mode = "undirected", weighted = TRUE, diag=FALSE)
i96e <- set.vertex.attribute(i96e, name = "group",value = col)
visIgraph(i96e, idToLabel = F, layout = "layout_nicely") %>%
  visOptions(highlightNearest = TRUE, selectedBy = "group")

Then I wanted to do this where the labels will not be shown. Only when you hover over the nodes. So when I tried applying the hover option from @lukeA, which is below, the colors didn't display:

 visOptions_custom <- function (graph, width = NULL, height = NULL, highlightNearest = FALSE, 
    nodesIdSelection = FALSE, selectedBy = NULL, autoResize = NULL, 
    clickToUse = NULL, manipulation = NULL)

    if (!any(class(graph) %in% c("visNetwork", "visNetwork_Proxy"))) {
        stop("graph must be a visNetwork or a visNetworkProxy object")
    }
    options <- list()
    options$autoResize <- autoResize
    options$clickToUse <- clickToUse
    if (is.null(manipulation)) {
        options$manipulation <- list(enabled = FALSE)
    }
    else {
        options$manipulation <- list(enabled = manipulation)
    }
    options$height <- height
    options$width <- width
    if (!is.null(manipulation)) {
        if (manipulation) {
            graph$x$datacss <- paste(readLines(system.file("htmlwidgets/lib/css/dataManipulation.css", 
                package = "visNetwork"), warn = FALSE), collapse = "\n")
        }
    }
    if (!"nodes" %in% names(graph$x) && any(class(graph) %in% 
        "visNetwork")) {
        highlight <- list(enabled = FALSE)

        byselection <- list(enabled = FALSE)
    }
    else {
        highlight <- list(enabled = FALSE, hoverNearest = FALSE, 
            degree = 1, algorithm = "all")
        if (is.list(highlightNearest)) {

        graph$x$options <- visNetwork:::mergeLists(graph$x$options, options)
    }
    graph
}

I didn't know how to do the video but you can hover over each node and it will provide the label name.

How do I add the cluster color to the hovering option graph?

Thanks!

The following yields the desired result:

# ...
i96e <- set.vertex.attribute(i96e, name = "group",value = col)
i96e = graph.adjacency(g96e, mode = "undirected", weighted = TRUE, diag=FALSE)
i96e <- set.vertex.attribute(i96e, name = "group",value = col)

V(i96e)$title <- V(i96e)$name
visIgraph(i96e, idToLabel = F, layout = "layout_nicely") %>% 
  visOptions_custom(highlightNearest = TRUE, selectedBy = "group")
