Once someone submits the confirmation form on a calendar, there's an option for them to enter "Additional Information", which seems to then update the calendar invite description.
We need an option to turn this off because:
A) We have no control over if this question is asked
B) We have no control over when it asks this question (and the way this defaults into the clickpath it may stop many users from seeing the buttons to add the meeting to their calendar at the end of the calendar scheduling flow.)
C) The response data isn't stored somewhere like on the Contact record
D) We have no control over if/how the response is shared across communications (and the way it behaves today, it's strictly on the calendar invite description whether you want it there or not)
E) The way this "updates" the calendar invite right after they first receive it isn't a great user experience... they are basically getting two calendar invites in a row.
Honestly, a better option is to just create a field for this purpose. By doing so I can choose whether to have it in any given calendar conversion form, and it will store the response data on the Contact's record, and it will allow me to choose when/if to include the response data somewhere like an email/text communication. I would totally use this alternate solution IF we could turn off the default "Additional Information" option, but unfortunately right now that would lead to asking the same question twice.... once in the form, and once after they submit the form.
