I believe that will depend on the browser you are using. It is up to your browser to interpret that mouse’s implementation of right click.
Haven’t done a lot of testing, but here’s a version that should support copy and paste through Android’s menu. You will have to find the combination of double click and/or long hold that works for you.
This really only works in the standard cursor/pointer mode. I have set dpad center and the number 5 to both be “action keys”. Use either one to double tap or to hold. On my Android 15 emulator long hold works better; on my Android 11 emulator double tap works better. Then, hold the action key to drag/adjust your selection.
I’ll have to update the visual and duration for long hold; just hold until you see the little circle flicker and/or your text highlighted.
