assistive touch top button

The accessibility functions on the iPadOS are really helpful except for the fact, you cannot create an assistive touch shortcut to double press the top button.

surely this is an oversight on apples part as you either have to double press the top button or enter your password when you want to install anything.

Why can’t double pressing the top button be turned off so it just uses facial recognition, or make it so an assistive touch shortcut can be used.

having to use your password instead of double pressing the top button doesn’t really make it easier for those with motor problems.
