Graphql subscriptions

Hello developers,
I'm coming to you because I've got a big problem.

I'm coding a live-forum with a graphql api. I use neo4j-driver, @neo4j/graphql and @neo4j/graphql-ogm in nodejs. As a real-time app, my projet must use subscriptions to perform his prime function. In dev mode, I can use the graphql-subscriptions package, but for the production, I don't find anything for neo4j implantation. Is there an alternative ?
