@Foxy Sorry for any inconvenience.
You can use "Move & Zoom" to resize and zoom in for your iPad screen.
On your iPad, when you hold the white ring button on screen,
it will bring you into "Move and Zoom" mode
that allows you to pan and adjust the size of your screen with two finger gestures.
When you tap the white ring, it opens the shortcuts sidebar.
At the bottom of the sidebar, you can switch from "Draw" to "Move & Zoom",
and adjust the screen size from there as well.
