Whatsapp backup on icloud

Hello,

I accidentally deleted a chat on my whatsapp, i think 1-2 weeks ago.

my whatsapp backs up daily on icloud

so now when I have tried to restore my iphone to a previous back up from a few months ago...i still don’t get the old back up of whatsapp on which that chat will be available. My new back up on whatsapp keeps restoring.

Is there any way i can access my whatsapp photos from an old whatsapp back up on icloud please? To retrieve the photos from the deleted chat?

I would be very grateful if you could help me!

kind Regards
