Auto-maximize screen brightness while shooting (à la Lightroom Mobile)

This is a feature from Lightroom Mobile that I really like and miss. When you open the camera interface, LR Mobile will automatically maximize your screen brightness so you can see the preview better; when you exit the camera interface (e.g., to view photos), it will return your screen brightness to normal.

I always have my phone’s display brightness set to auto. When I hold my phone horizontally while shooting, my hand often cast a shadow over the phone’s light sensor, and my screen brightness would go all the way down. It always interrupts the shooting because I have to swipe down control centre to turn up my screen brightness (and then afterwards I’d have to turn the brightness back down).

This might not be an issue for those who always manually set their screen brightness, so I think having this as an ON/OFF setting (or maybe allow user to set their preferred screen brightness in the camera interface?) somewhere would be a nice QoL feature.
