Complaint Cannot add Discord username to identities

[Addams]

I am trying to add my Discord username to identities but it doesn't match the format somehow.
I believe the "'" is the reason, Any possible solution?

Can you add it without the apostrophe (') or the hashtag?

I tried without (') and can add it normally, so it looks like any name with (') isn't allowed there.
