Stream Deck+ Action for Get Brightness

Greetings Andreas. I would appreciate an action to get the current brightness setting of a Stream Deck+.

The reason is I want to toggle the brightness between off and its prior setting. I would use toggle power on/off except that turning the power off leaves the touch screen on (perhaps that is a bug) and, in any event, I want to keep the power on so that I can use a Stream Deck button to turn the brightness back on.

Thank you!
