How to create a relationship property in graphql type definitions using neo4j-graphql library

Using neo4j-graphql library, from property graph models we could create a graphql type definitions.

For example, for the contrived imdb graph model below:

enter image description here

We could create graphql type definitions like so:

type Movie {
    movieId: ID! 
    title: String!
    actors: [Person] @relationship(type: "ACTOR_IN", direction: IN)
}

type Person {
    personId: ID!
    name: String!
    actorInMovies: [Movie] @relationship(type: "ACTOR_IN", direction: OUT)
}

Notice how @relationship annotations could be used to establish relationships between different types.

However, neo4j also allows you to create relationship properties as well, as shown in the example below: enter image description here

I can't seem to find any neo4j-graphql library document that explains how to achieve this. Please suggest. TIA.

Relationship properties are not supported by the Neo4j GraphQL Library. We are working on it right now and you can see the RFC for it here https://github.com/neo4j/graphql/pull/193.
