Stop auto connect with Apple ID when sharing files between macs.

I have a 2017 iMac and a M4 Mac mini. From Finder Network on Mac mini the iMac is shown, however the “ Connect as: myappleid” is the share login option. If I disconnect and use connect as administrator the pop up box shakes. I never want to use my Apple ID for my LAN file sharing nor iCloud ever. From another post on this community the steps to fix do not appear on Monterey. I can’t get to advance options. I was able to use Connect as on the Mac mini into the iMac a week ago without issue. I used Screen Sharing on the Mac mini to remote in to a Mac outside of my LAN could doing so have caused this issue? Thus far googling has proven useless. Please help. Thank you.
