I have sent a longer response over messages.
In case someone else can correct me, I'll include one section here
While I’m not sure about the best way to do that, I think this page has the contact information for reaching admins: https://legal.lemmy.world/bylaws/#22-community-mod-removal . You can see the contact options in section 22. While the text in that section talks about mod removal, later on (section 25) they say to use the same contact info to reach admins for other purposes.
