WhatsApp:No backup found error

Hi,

I have had a problem with my whatsapp and I am trying to recover my chat history from

iCloud. I backed up my iPhone on iCloud two 1days ago. I trying to restore different way but couldn’t restore.

Now when I signed back into iCloud and installed Whatsapp again and gave my same old number, Restore from iCloud saying "No

Backup found".

But I can see the Whatsapp backup of 1.2GB in Settings>

iCloud> Manage Storage> Backups. It has messages from more than 2-3 years that I'm saving it.

I have enough storage space to restore

and I tried with connecting to the different Wi-Fi and cellular data.

My current iOS version is 16.3

Any help or manually to get back my backup would be highly appreciated. what should I do now?

Thank you
