Thanks for the PR @jiteshdhamaniya !

We should show the group in multi-select toolbar as you already mentioned in the issue afterwards.

@mtias in order to add it to multi-select toolbar, we need an icon, is there any existing icon we can use?

I guess just the Group block icon would do just fine but let's get some thoughts from @jasmussen or @jameskoster maybe?

We should not move the position of items in the ellipsis menu, which can be disorienting and feel arbitrary. We should add a shortcut for "group" in the toolbar, maybe next to the ellipsis menu for multi-selection. And yes, the group icon should be used.
