fragment rowHeader on GridRowEdge {
  ...rowHeaderExpandIcon
  ...addItemRow_gridRowEdge
  node {
    ...rowHeader_Row
    id
  }
}

and

fragment rowHeader_Row on GridRow {
  id
  path
  hasChildren
  pmEntity {
    id
    name
    model {
      id
      slug
      displayName {
        singular
      }
    }
    permissions {
      hasEdit
    }
    ...pmEntityIcon
    ...requirePmEntityUserPermissions
  }
  ...pmEntityAccessIndicator_rowHeader
}

Is it possible to reconstruct the typedef of this query?

My main question is the id, path, hasChildren belongs to Node or the GridRow? Like how does this work.
