Hi, how can I unlink my K380 keyboard from Options+ Beta so it could be used in Options again?

I just wanted to give Options+ Beta a try but I realized my M720 mouse wasn't supported, so I decided to uninstall Options+ Beta to continue using Options (until M720 gets Options+ support).

But now I can no longer control my K380 in back in Options. This is bad because this means I can no longer make my keyboard automatically switch to my other devices using Flow.

Please either help me unlink my K380 keyboard from Options+ Beta, or add support for my M720 mouse.

I look forward to hearing from you as this is breaking my workflow and productivity.
Thank you,
Crys
