Archiving Assets

I want to archive certain assets so they can’t be used in other games without my permission, so I went to the creator dashboard to begin the painful process of manually archiving each asset.

The problem is the archive asset button seems to be gone, and I thought I’d need to opt into their asset privacy beta to change the permissions.

Problem is, all my assets are now labeled open use for everyone and I can’t change their privacy at all.

This is the opposite of what I want.

How do I remove my assets?
