Visual feedback when enabling or disabling groups

Hello everyone, new user here!

I am building myself a smart dial similar to the one on a Logitech Craft keyboard that sends keystrokes to my computer and triggers Keyboard Maestro stuff.

I am wondering if there's a way to display on screen visual feedback every time I enable/disable Macro Groups, similarly to how apple displays visual feedback for Volume/screen brightness, with transparency if possible.

Why? Since the dial is only able to send 4 keystrokes (Right Rotation, Left rotation, Touch Tap, and Press Down) I would like to use one of them to change my Macro "Set" but having multiple "sets" without visual feedback is impossible.

Is there a way to achieve this ?

You will have to manually issue the display/notification, but yes, it can be done.
Here are a couple of choices:
