Proper way to delete items

Help

I have a GraphQL schema that looks like this:

type User {
  firstName: String
  lastName: String
  email: String
  groups: [Group] @relation(name: "members")
}

type Group {
  name: String
  members: [User] @relation(name: "members")
  startDate: String
}

This creates an index called members_by_group and a Collection called members.

If I preform a deleteUser mutation:

mutation{
  deleteUser(id:"329431630822244946"){
    _id
  }
}

The user is not “unlinked” from the group, and the members collection still contains the following record:

{
  "ref": Ref(Collection("members"), "351058485137375832"),
  "ts": 1671054310890000,
  "data": {
    "groupID": Ref(Collection("Group"), "329795413068481106"),
    "userID": Ref(Collection("User"), "329431630822244946")
  }
}

This results in Instance not found errors when Querying the group:

findGroupByID(id: $id){
    _id
    startDate
    members{
      data{
        _id
        firstName
        lastName
      }
    }
  }

What is the proper way to delete items via GraphQL so that the corresponding collections and indexes update correctly? Do I need a to create a function? What would a cascading delete function in FQL look like? Thanks in advance.
