I recently broke my Google Pixel 3a and now I got a new phone (Samsung Galaxy S9, running on the same Android version, Android 10). Now I would like to restore my WhatsApp chats from my old phone. I could not manage to retrieve the local chat backup from my Pixel phone and I did not store any WhatsApp backups on Google Drive. However, I have a phone backup called 'backup of Pixel 3a' in my Google Drive. I was able to restore that backup on my new phone. As it seems, that backup contains my local settings, call log and which apps I installed on my previous phone. Apparently, some app data is also included in this backup.
Now my question is: Is there any way to retrieve my WhatsApp chats from this phone backup on Google Drive?
