show a popup with group name when switching groups

The issue:

I would like to achieve the same kind of effect that the one on this short clip, i.e. when switching groups, the name of the group appears somewhere on the screen.

I have two smaller issues indeed:

1. I’m trying to use the builtin hooks to do that, e.g. @hook.subscribe.changegroup but there is no doc on the hooks doc page. I just found the commands API doc where I might be able to find what i need, i.e. extract the name of the current group, but it was not trivial… Maybe adding a direct link to the commands API would be helpful! And then, i do not know if using libqtile.command.client.InteractiveCommandClient().group.info() is the prefered way to extract the name of the current group 🤔
2. any idea how to do such a small and ephemeral popup? Could not find it inside the xmonad config of the clip… And using things like dunst would not be as pretty as that 🤔

Cheers 👋 😋

    qtile.call_later(1, layout.kill)  # kill popup after 1 second

            text="TEST",
            row=0,
            col=0,

    layout = PopupGridLayout(

    layout.show(centered=True)
