Probably bad luck for you that the mod is not compatible with your device, got the same problem but worked for jnonymous so it works fine for other devices.I don't have a mod menu, the game does not ask for permission to apear on top at all
If I had to bet, I'd bet that the mod has issues on bigger screen. I can see already that the game has some corners not being displayed. So probably the floating menu is on the edge that isn't being displayedProbably bad luck for you that the mod is not compatible with your device, got the same problem but worked for jnonymous so it works fine for other devices.
