Hey

What I’m trying to do is to tag graphql responses based on their \_\_typename and instances returned. So let’s say we have a query like this:

```auto
query {
    getUsers(limit: 2) {
        id
        username
    }
}

```

Assuming this query is going to return a User, The desired tags looks something like User:1, User:2  
How can I add \_\_typename to every query using a Apollo server plugin?
