Android’s work profile makes it possible to separate your personal and work life on a single device, and Google’s done a lot to make the work profile feel as integrated as possible. For example, when you have a work profile enabled, the Android launcher adds a separate tab (shown above) that contains all your work apps. In Google’s own apps, you can easily switch between your personal and work profiles by tapping your avatar and then selecting a button in the pop-up dialog. Now, Google’s making it even easier to switch between your profiles.
When Google added an account switcher to its apps way back in 2019, they made it possible to switch between your Google accounts by swiping up or down on your avatar.
I'd actually forgotten it existed TBH. I haven't used many Google apps since ages, and that gesture only works on Google apps. Never seen other apps make use of that either.
