How to auto assign a plan only team to new issues as they are created?

We are using Plan only teams in Jira planner, and assigning these teams to issues.

The teams are created in Plans with the issue source being their allocated board. Plan only Team 1, issue source is board 1.

When a new issue is created on a board, how do auto assign that issue in my plan to the team.

For example, an issue is created on board 1, plan only Team 1 needs to be assigned to it.
