Adding a Tab to a Team Channel through Flow

问题:

I'm trying to use Flow to add a SharePoint List Tab to a Channel in a Team. But while I can add a Tab, the Tab is always blank.

I've tried both Microsoft Graph Explorer and Flow but I can't seem to configure the tab to show my SharePoint List. Or any other app for that measure. The tab is always blank.

I've followed the POST from the API

POST https://graph.microsoft.com/v1.0/teams/{id}/channels/{id}/tabs

Body:
NOTE: 2a527703-1f6f-4559-a332-d8a7d288cd88 is the TeamsAppsId for Sharepoint and Lists which I gathered from the API

{
  "displayName": "My Contoso Tab",
  "[e-mail]" : "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/2a527703-1f6f-4559-a332-d8a7d288cd88",
  "configuration": {
    "entityId": "LIST ID HERE",
    "contentUrl": "https://www.contoso.com/Orders/LIST ID HERE/tabView",
    "websiteUrl": "https://www.contoso.com/Orders/LIST ID HERE",
    "removeUrl": "https://www.contoso.com/Orders/LIST ID HERE/uninstallTab"
  }
}

I get a 201 Created but when I go to my Team and check the Tab in the Channel, its blank and I need to manually set it up from Settings.

When I run the call on explorer using Sharepoint Website AppId (com.microsoft.teamspace.tab.web) I get the following success response

But when I go to the Teams List Tab I just created I see this

Any suggestions on how I can tackle this?
