How to do the right click eraser trick in mspaint on windows 11?

Hi all!

I have an Inspiroy WH1409 V2, and am running on windows 11 and its version of ms paint.

If you know MSpaint you know the trick with setting color 2 to be another color and using the eraser tool to color over lines. I used to be able to do it on my windows 10 pc where I had a button on my tablet to hold right click, and wherever i dragged my pen it would recolor. now it doesn't work.

basically, is there a way to set a button to be a hold right click, rather than a press? (i think this is the problem)

I hope this makes sense!!! thank you !
