Feature request for hiding the tab bar

I am using vertical tabs on Brave. But I wish to make it completely hidden and want to toggle the view by hovering the cursor at the side or any keybinding. Is it possible? How can I do it?

For example, we can hide both the Tab bar and Top bar on Zen browser (shown in the screenshot below). It gives a clean, non-distracting look. I wish to have this same feature on Brave, at least for the Tab bar!

Brave will become Vivaldi at this point. But for some people might work (not my case)
