leave a closed third party board

[Mikael Byström]

Obviously it's too much to ask for that when a board is closed, members are automatically removed, or given a way to leave.

I need to leave a closed board that was operated by a now defunct third party, that keeps showing up in search results. Why would anyone want results from a non-usable board?

There was a way linked to in Leave a board in Trello, but of course that is closed now. 

So, how do you leave closed board you're just a member of?

Hello @Mikael Byström 

Google AI provided this response:

To leave a Trello board (even if it's closed or you're a guest), open the board, click the three dots (Menu) in the top right, find the "Leave board" option at the bottom of the menu, and confirm to remove yourself from it; if you can't leave because you're the last admin, you must first add another member as an admin before you can leave. 

I am not a member of any closed boards against which I can try this.

Does this process not actually work?
