Magic Mouse not clicking

I’ve had the Mouse since 2014, and only noticed a problem with it last year. I can move the mouse and the cursor follows, I can scroll too. The problem is when clicking or selecting stuff (e.g. searching for something on Google and then selecting the website I want to visit). How can I fix it? I’ve checked the settings of the Mouse, but it all seems fine, and I’ve tried playing around with it, but there has been no difference.
