Remapping buttons on mobile

[Erinalope]

Had this issue a couple times on my retroid pocket 4 (android handheld) where one easy to press button can delete your tool or item. Makes me wish I could remap or disable buttons.

also, what control scheme should I use? I use the invisible joystick and button but really i want no touchscreen controls aside from drag/drop and pinch to zoom. Seems like theres no options for “I use a controller”
