Help me with bluetooth problem

I was a linux user months ago and everything was good but when i bought a bluetooth mouse it didnt showed up. So i switched back to windows and there the bluetooth was working but i still liked linux more than windows.So i installed manjaro on my computer as dual boot.When i click the add icon in bluetooth in setting it only shows scanning and it keeps looping nothing is to be found.My mouse is logitech m337.What to do i don’t know someone please help.I would be very grateful because i don’t want to go to windows again.I’m tired of this.
