Can't wait to try this on Android. But what you try to do on Twitter you can do by default if you enable Swipe Gestures in settings as show in the video.

And as of Android 14 I believe, under the Developer options, you can turn on Predictive Back Animations (not shown in vid), which preview the previous window when swiping to go back.
