Enter picture-in-picture mode from installed Brave apps (PWAs)

I really like the picture in picture mode from brave. But I “Installed” the youtube PWA, and it doesn’t have an option to enter picture-in-picture mode.

I can still open brave and enter picture-in-picture mode for the playing youtube window, but I feel like I should just be able to do it from PWA window.

basically this feature (from the regular browser)


should be available here (on the PWAs top bar)


Sorry if this is a duplicate.
