This seems like a Fediverse question: spouse has a Logitech G502 HERO mouse and wants to configure one of the buttons to act as a shift key, which seems to be a rare goal. I've found no helpful forum posts about doing this on #Wayland at all. (Running #Bazzite #Linux.)

Piper is failing to make changes, looks like maybe a timeout. However, on-device profiles seem to be set up right, per Solaar. Going to dive deeper into logs soon, but thought I'd see if I could snare any gaming-on-Linux experts.
