Not being able to make WhatsApp backup

Hello,

Since I have the iOS 16 Beta installed on my iPhone, I'm unable to create a WhatsApp chat backup.

It keeps saying to log in to iCloud, which I am. Weird thing is if I go to Settings> iCloud. I can't find WhatsApp there to enable or disable it.

Now what?
