Bug Description

When I try to perform a mutation of an user using the userPermissionPlugin like :

mutation UpdateUsersPermissionsUser($updateUsersPermissionsUserId: ID!, $data: UsersPermissionsUserInput!) {
  updateUsersPermissionsUser(id: $updateUsersPermissionsUserId, data: $data) {
    data {
      confirmed
      username
    }
  }
}

with these variables it doesn't work, I get a not found error:

{  
  "updateUsersPermissionsUserId": documentID-OfAnUser, // e.g. "g1234o33xzjghhz9obw0brhy"
  "data": {
    "relation": [documentID-OfAnEntryOfTheRelationalField],  // e.g. "g1234o33xzjghqssdbw0brhy"
  }
}

but with these it does

{  
  "updateUsersPermissionsUserId": ID-OfAnUser,  // e.g. 1
  "data": {
    "relation": [ID-OfAnEntryOfTheRelationalField], // e.g. 3
  }
}

The problem is that I can't get the id of the relational field entry with graphQL as only the documentId is exposed via the api.

Steps to Reproduce

1. Create a User role
2. Create a Collection type - for example "allergies"
3. Add a relational field between the two, user has many allergies
4. Add some entries to the allergies collection type
5. Try to add new entries to the user relational field via graphQL

Expected Behavior

I expect the graphql mutation to work with documentsIds
