Mouse custom settings not working in figma, instead same settings working in all other apps like PS, AI etc

Quite surprising that I started the discussion and I am posting the solution :blush:.
Try this out- When you go to the option of adding an app for custom settings in Logitech option+ or in your case any app you use ,it shows you the default list of all the on your PC and down below is the option to browse and select the app. I was encountering the problem when I was selecting the app from the default list but, I tried browse option and selected the app from my desktop shortcut I use to start figma then suddenly all the custom mouse settings for figma starts working.
Try this may be it will work for you also, I hope so
