Edit Webinar Invite

[AC_]

After setting up a webinar, with registration required, the invite created has the salutation, "Hi there" auto populated - is there a way to edit this?  I know how to edit other components of the invite, but not this salutation.  Thank you.

I apologize this is not an answer to your question, but I am trying to determine how to edit the invite.  Can you help?
