I suggest you to add a Google chrome floating app
In my opinion it would be so much easier and practical because a lot of people use chrome and having it available also among their floating apps would be good also because we would have all our data already saved and so our favourites pages.
It’s not possible to float normal apps due to limitations of Android platform. We are currently looking for solutions for the newest Android versions. but we can’t (nobody can) float normal Chrome on all phones. It cannot be done.
