Inndob Cluster - Automatically collect the output from mysqlsh?

Is there a way to take the output from mysqlshell and use it in a script or similar. I have set up a basic cluster for testing (3 x MySQL 8.0.27 databases, running on Debian 11). I am now trying to find a way to capture the output from mysqlshell's cluster.status() output. As an example, from inside mysqlshell I can run: cluster=dba.getCluster() cluster.status().defaultReplicaSet.topology['test-1:3306'].replicationLag to get the current replication lag. I would like to capture that so it can be monitored automatically. I assumed most of these statistics would also exist in the performance_schema or mysql_innodb_cluster_metadata databases somewhere, but I can't see them. Is there a way to do this?
