How to enable "assignee" and "labels" fields for "create a ticket" in the Atlassian cloud addon

How to enable "assignee" and "labels" fields for "create a ticket" in the Atlassian cloud addon for Gmail?

Right now,

1. I need to create the ticket without an assignee and label
2. Click "Open the ticket in Jira"
3. Update the assignee and label

It will be time-saving if I could add the assignee and label while creating the ticket inside the Gmail itself.

Please let me know if I can modify the default fields for the Gmail addon. thank you!
