Is there a way to map single button presses from these bluetooth tiktok scrollers/controllers that are a dime a dozen? I don't want to include a link and be marked as spam, but search for "bluetooth tiktok ring controller" and you will find tons. As far as I can tell, pushing and holding the buttons on these emulate keyboard presses and can be remapped pretty easily. The single press toggles seem to be touch swipes without a click, so not as easy. With these things going for $5 a pop on Amazon, it seems like there would be a pretty large use here. Happy to send you one to test.
it might work, either via the keyboard shortcut section in BTT or by using the "Generic Device Support"
