UPDATE 7th December 2020
We appreciate the merit of this issue, but wanted to update you all that at this point in time, it is not on our roadmap in the foreseeable future. The solution here is not as straight forward as we would have liked and we are intending to bring many other improvements to the product that are at this point prioritised higher than this one.
We will be reviewing this again within 6-12 months and will continue to update on this ticket, so stay tuned.

Currently, when users go to Settings -> Request types --> Edit fields --> Add a field, Request Participant field is not in the list even they've added this field to the issue type by editing the create screen for this project..
As a user, I'd like to display Request Participant field in the Create Issue screen in customer portal.
Why this is important
It would save a considerable amount of time to be able to add participants while creating the ticket instead of sharing it later.
Share the ticket with the request participants after the ticket is created.
