Whatsapp backup in iCloud drive

Hi All,

Need help with whatsapp chat backup, I was setting up the new phone. Took an icloud backup of whole device apple provide a temprory icloud space to support it. I never had icloud backup chat on in whatsapp app. It was only backup today with a whole device backup.

Is there anyway I can get whatsapp chat back in my new phone? I am locked out from my old phone as I was trying to login whatsapp in my new phone, when I checked to restrore chat from icloud during this process, it says no backup found.

Any help is appreciated.

Thanks.
