Canva Archive and Restrict Access

I need to secure a collection of Canva files, including images and videos. The freelancer will transfer these files into a secure archive where the original creator can no longer access them. I can give you my canva credentials to do this so I am the owner of the new archive. There are 12 images in one link, and 4 videos in another. I don't think this is hard, but I don't know much about Canva, and the freelancer who created this work is really jerking me around. I've paid for it, we are in dispute status, and I'm concerned he's going to delete everything so this must be done in the next 24 hours.

Please let me know if you have any questions.
