How do I add an additional person to a meeting I have already scheduled?

@marianswer - If you do not require authentication in your meeting, you can just forward the meeting link (or add them to your calendar invite) and they will be able to join your meeting.  If you do require authentication, edit the meeting and add their email to the participant list and they will get an invite.
