How to return a Neo4j schema with relationship names, from node names and to node names in one table?

Question

I need to return a schema from a Neo4j database which contains all relationship labels, from-node labels and to-node labels. The table template shall be like this:

relationship labels, from-node labels, to-node labels
has_b,a,b
has_c,a,c

I noticed that the query call db.schema.relTypeProperties only returns limited fields, such as relType, propertyName, propertyTypes, mandatory. The fields missing are from-node labels and to-node labels.

BTW, this gives me a hint on solving my question. However, this method is proposed for returning nodes instead for relationships.
