How would I remove the verified checkmarks from one invite code in retrospect?

How would I remove the verified checkmarks from one invite code in retrospect? I joined a chat via InviteBot, now I have plenty of people introduced via InviteBot as somehow trusted:

Since I don’t know who any of these are and obviously InviteBot isn’t a person that I personally trust either, I would rather not have the users introduced that way to be marked verified unless I actually verified them. Ideally, the pgp keys should remain known and tracked and prompting warnings on change, but simply without that verified check mark.
