Need to delete an aurora postgress reader attached to a cluster with no downtime

Need to delete an aurora postgress reader attached to a cluster with no downtime. The reader has active connections. how do i do this?

You first need to ensure that the reader is not receiving any new connections by updating your application’s configuration or load balancer settings. Allow existing transactions on the reader to complete and disconnect active connections. Once all active connections are cleared, you can safely delete the reader instance from the cluster.
