How do I fix device re-assigned to a different Apple ID on new user creation?

So, we got a new mac mini yesterday.

I set up a few accounts, for wife and kids.

Somehow, the device got reassigned during setup to my daughter's AppleID.

Eg. in Find My, it's listed as hers.

How do I fix this?!?

From her account I only see the option to erase the device. I definitely don't want to erase the device, after hours of setup. I just want to re-assign it again to my account.
