iCloud storage full but I've been deleting files?

I have a Zoom Workplace Pro account. I accidentally deleted a file that I have 30 days to recover while it's in the Trash. I can't recover it as my iCloud storage is full, and it says to either buy more storage or delete files. I've deleted multiple files and hardly have anything saved, but it still says my storage is full. Currently:  14.62 GB of 5 GB, 9.62 GB over current capacity.

What can I do to recover the file without buying more iCloud storage?

Really appreciate you're help!
