Currently, when you try to create a Jira issue from a Whiteboard, the required custom fields from a selected Jira project/Issue type are not displayed in the 'Create a Jira issue' modal, even if you click on 'show more fields'.

Instead, you will see a warning message " Some fields require more information. Continue in Jira" and clicking on the button "Create in Jira" will just redirect you to the Jira project's queues.
