Microsoft Arc Mouse Cannot Bluetooth Connect To Macbook Pro

Hello Community.

I am a MacbookPro user using macOs Catalina 10.15.7 . Today, I accidentally clicked in x beside on the arc mouse in the bluetooth menu and now my mac cannot find and reconnect the arc mouse back to the computer.

I have tried restarting the mouse and computer and checking batteries for the mouse. All seems to be in place, the problem is just that the mouse can't connect.
