Double tap on pen to change from pen to eraser on Android Tablet and Palm rejection

I have OnePlus Pad 2 and I have a stylus which has a tap function just like apple pencil which allows the user to change from pen to eraser while writing in their notes app. However on Excalidraw this feature doesnt work and even the palm rejection doesnt work. Kindly add this feature.
