[Feature]: Support for Customizable Keybindings for Enabling Keymapping

Is your feature request related to a problem?

Hello,
I am currently using PlayCover to play the game Honkai: Star Rail. I noticed that enabling keymapping with the option key is the default setting, but I believe adding the capability to use the right mouse button to enable keymapping could be a very user-friendly option. This change could significantly free up keyboard operations for users when playing Turn-based games.

Describe the solution you'd like

Would it be possible to add support for customizable keys or buttons to enable keymapping within Playcover (e.g., we can use right mouse click instead of OPTION)?
This feature would greatly enhance user experience by providing more flexibility in how they interact with the game.

Anything else?

Thank you for considering this feature request. I look forward to any updates on this matter.

Start by locating the PlayTools entry point that handles the current Option-key action for enabling keymapping. Define how customizable keyboard or mouse-button triggers, including the requested right mouse button, should be configured and persisted; the feature is done when users can select an alternative trigger and use it to enable keymapping.
