MX Master 3 gesture button click is not working on MAC OS big sur 16inch Macbook pro.

I couldn't find search option so I set keyboard shortcut of cmd+space to trigger spotlight on click of gesture button. It worked while the logi options + window was open but as soon as I closed it. It stopped working. It was the case for any action that I set up on click of gesture button.

Please resolve asap or I will have to uninstall it.
