Google updates a Play Store feature and Nearby Share using Material You designs
The update hasn't been completely rolled out yet as the Play Store Google Account switcher on this writer's Pixel 6 Pro (running the Android 13 QPR2 Beta) still has not been updated.

Also getting a taste of the Material You update is the Android Nearby Share feature. With Nearby Share Android users can share files and apps with other nearby Android phones using Bluetooth and Wi-Fi. Also noted first by 9to5Google, the Material You update adds animated shapes that expand in back of your avatar while the app looks for nearby devices. Available devices are highlighted using a Material You icon. And when you're in the midst of receiving a large file (like a video), a parade of Material You shapes continuously circle around the middle of the panel.

The Material You update for Nearby Share arrives via a server-side update alongside the latest version of Google Play Services. You could consider Nearby Share to be the Android version of the iOS AirDrop feature. To access Nearby Share on your Android phone, open the Files by Google app and tap on Nearby Share at the bottom of the screen.
