As of Feb 2023, The only way to create a team-managed project is by passing a template key. Unfortunately, the create project jira cloud rest API endpoint only exposes these templates for Jira Software.
It is my understanding that It is impossible to create a team-managed jira work management or jira service management project as all the template keys listed in the API documentation would result in a company-managed project.
Is it possible to create a team-managed Jira work/service management project using the REST API?
Thanks
