Hi, does anyone have a solution for this?
Do you want to configure custom context menu items? ( you probably tried adding custom context menus in BTT, but haven't any active at the moment)
Which version of macOS are you on?
Mac OS 15.2
I only have Middle Mouse for my MX master mouse button for Menu bar context menu.
its also appeared on finder.
you might have tried the finder extension previously. You can disable it in System Settings => General => Login Items & Extensions => File Providers
Solved, Thank you ! 
Btw, with the message showed up on context menu, is that mean that its possible to add my own function on general or specific app right click menu?
