Clear Cache Button in Menu

Hello. I would like to ask if its possible to add a Clear Cache Button ( i'm using wp-rocket atm) in the side menu for the clients to use.

I've tried adding a toolbar in the side menu and using the wp rocket option but the problem with that is when the user goes in the post page, the toolbar adds an selection the preview the posts in the website. + if you want to clear cache with this option you need to hover over the wp rocket choice and choose the option clear cache.

Optional i would like to have a button for the user to click on.

Thanks a lot
