Prisma

Q: At which stage in the RP can I create a node that references the newly created node? Only in `TRANSFORM_PAYLOAD`?

Background: I want to create a child node server-side when a node of a certain Type is created, and be able to query that right away:
```
mutation {
    createGame {
       id
       gameState {
          status
          nextTurn
          ...
       }
    }
}
```
the `GameState` node would be created on the server, but I'm trying to figure out where I can do that, and how I can get it into the result
