Amazon Managed Workflows for Apache Airflow - Policy to restrict user access to specific DAG?

I am trying to use Amazon Managed Workflows for Apache Airflow. I see that only authorized IAM users can log into your Airflow UI because of integration with IAM.
Is there any way to restrict the access of the user to a specific DAG within the Airflow(MWAA)? If yes, how to write the IAM policy for this?
