how to make icons in google custom menu

Question

In google apps (docs, sheets, etc)

Is it possible to make icons in custom menus similar to ones in the insert menu? If so how would I go about it? html service?

The ones next to chart, link, image or even next to bold, italic, etc

Thanks

There is no exposed method to put graphic icons in the menu. The best you can do is use Unicode characters such as ✘ and ☢
