Mouse clicks don’t work in menus or inventory on iOS using AssistiveTouch

I’m playing Minecraft Bedrock Edition on an iPhone 16 using a Bluetooth mouse through iOS AssistiveTouch.

My mouse works during gameplay. I can hit things, break blocks, and place blocks, but I cannot click any buttons in Minecraft’s menus, settings, or inventory. I also cannot click Play on the main menu.

The pointer is always the gray AssistiveTouch pointer, not a normal Minecraft mouse cursor. Clicking menu buttons and inventory slots does nothing, even though the mouse works elsewhere on my phone. Touching the screen with my finger still works normally.
