Hey,
I'm trying to add to a form - a "CC user" field where users can add other users to the ticket they are raising. I've only been able to do this in the following way (see screenshot) The problem is the users can't add email addresses here it seems. Is there a way to allow them to add either emails and / or usernames? They've been given permission to invite people to the ticket.

On the ticket itself they are able to add more people CC'd in, and I'd like this exact field to be on my form:

Is there a way to do this?
Thanks in advance for the help!
