List solr replica properties

I'm looking for a way to list all properties on a replica. I checked this page: https://lucene.apache.org/solr/guide/7_6/collections-api.html But no such thing is mentioned there. Only adding, editing or deleting existing properties, but no way of listing all of them. How can I find out which properties have already been set on a replica? EDIT: Found them in zookeeper. Use command: zkCli.sh get /solr/collections//state.json
