how to restore whatsapp messages on iphone from google drive

Just reinstalled whatsapp app!

Wanted to restore the backup from iCloud

But I accidentally pressed the wrong button and clicked on backup, causing the backup on iCloud to become a file that was never backed up at all ......

Is there any way to salvage it please?

I was using an Android phone before, so I still have backups in Google Cloud;

Would like to know if there is any way to restore Whatsapp messages on iPhone from Google Cloud hard drive!

Thank you.
