If you can get your agent of choice to run up the app in an emulator and navigate the whole thing taking screenshots then tasks like edge-to-edge can be pretty hands off.

The way I did it was to firstly get accessibility identifiers on everything. Then have it record everything I do on an emulator to navigate the entire app. Then left it for a while to work out how to actually use the app via the emulator. Once you have this sort of baseline. A lot of changes are really quite pleasant. I often ask for an HTML gallery of screenshots covering a few device sizes as the step before I bother running it on a device myself.
