Description:
On the M3 components website, it is stated that a check icon will be displayed to indicate selected state.
However in the docs there's no mention of this. There is the app:icon property which sets the icon, but doesn't display the check icon when a button is selected in MaterialButtonToggleGroup.
I'm also curious about this. It is rather strange that the Material Design website prominently shows this checkmark, but there does not appear to actually be a way to show it without manual work.
