WhatsApp states that I have end to end back up encryption activated so I cannot download my backup from iCloud

I have my iPhone set up for iCloud back ups and WhatsApp is asking for a password or 64 digit encryption key (that I dont have) in order to restore my WhatsApp chats. It is clear from searching this community and online that I am not the first person to experience this issue. Wondering if there are any work arounds that can be shared?

I am looking for some sort of iCloud related tip or work around as the WhatsApp app says that they will delete my data if my next password attempt is incorrect. Can they do that as the 7+GB are stored on my iCloud, and I simply need to match the password or encryption key to "unlock it".

PLEASE do not suggest "ask WhatsApp" because they do not reply to inquires.
