I'm not sure about how much sense it makes to create a relationship challenge after the relationship has been terminated - but then sending or requesting challenges via Messages is not supported, so you are supposed to use a side-channel for which termination doesn't matter?? idk

When I restricted it during the relationship termination implementation, I didn't understand how those challenges work
