Keep the toolbars from reappearing after switching aps

Hello Brave team, what a wonderful browser you guys have created. Can I suggest a small feature? Can you make it so that the top and the bottom toolbars don’t reappear every time after I switch between apps. You know when you scroll down a web page the toolbars disappear right? And then if you leave the browser, go to another apps, then when you come back to the browser the toolbars reappears. I don’t want that, I want it to stay hidden until I scroll up to make it appear when I need it. Like in Firefox or Samsung internet browser. Can you consider this request. Thanks for your time, and keep up the good job.
