I banned someone mistakenly and would like to unban them, but I don’t find Lemmy’s layout super user-friendly and I can’t find where to go to do that. If it matters, I’m just a community moderator, not an instance admin.
Using the default lemmy-ui you first have to find a post or comment that the user made in your community. Then you should be able to use the pop-up menu for that post/comment to unban them. It may be helpful to go to the user’s profile and search for a relevant post or comment there.
If you are comfortable using the API directly, you can send a POST request using a tool like curl or a browser plugin like RESTED. The site below provides a reference for formatting Lemmy API requests. Set ban=false. It’s a pain, though; you first need to get the community_id, person_id, and your session authentication cookie as inputs.

If it’s not there, you can always ask instance admins to do that
