Configure button of stylus as keyboard shortcut?

Hi, I have a galaxy tab s7 and I´m planning to buy the Wacom One Pen that has two buttons. Is there a way to configure one button as a shortcut of “tool radius” ??? The default hotkey is “X” . Maybe using a remapp app ??

You can configure the shortcut in the bindings menu.

Thanks. I can configure shortcuts as bluetooht keyborard buttons, but not with the spen button. Will be different with the Wacom One Pen ??

No idea how it works with Android but it probably won’t work.
