Apollo Server and @neo4j/graphql: Automatically created Where Type is missing fields (Graphql)

Question

I defined a graphql schema in apollo server with @neo4j/graphql likes this:

type User {
    name: String
    status: String

Later on I added a new field:

type User {
    name: String
    status: String
    isAdmin: Boolean

Now I query the API like this

  query Test {
    users(
      where: { 
        isAdmin: true
      }
    ) {
      name
      status
      isAdmin
    }
  }

This does not work with the Error Field "isAdmin" is not defined by type "UserWhere".

This was the first thing that generated some confusion, because I never defined a UserWhere. I then checked the SDL in the Apollo Studio (https://studio.apollographql.com/sandbox/schema/sdl), which gave me the first clue: There are many auto-generated types.

Input UserWhere {
  OR: [UserWhere!]
  AND: [UserWhere!]
  NOT: UserWhere
  name: String
  status: String
}

So this UserWhere type is lacking the isAdmin field. Querying with where on name and status works perfectly fine.

So now my questions are:

1. Where can I find documentation on how Apollo adds those fields? I was having a hard time.
2. If I restart the server, I would have expected that the UserWhere would change with the new fields. IsAdmin can be selected and returned just fine, but I still cant filter it using where. Where is the problem? How can I automatically generate the UserWhere with the new fields?
