And again for you and everyone else:
If you don't plan to update your app on Aug 31 or early Sept, NO action is required from you.
Note:
However, if your app is still targeting API 30 (which is not the case for you, since you only recently created and uploaded the app), you should at least update it with targetSdkVerion = 31, otherwise your app will be available for users with Android 12+ devices will no longer be listed in the Play Store as of Aug. 31, 2023.
