Getting linked board items

I am trying to figure out how to return linked_items for two boards. Here is my query:

boards(ids: [87610960]) {
    name
    items_page(limit: 10
      ) {
      items {
        id
        name
        linked_items(link_to_item_column_id:"connect_boards" linked_board_id:87898724) {
          board { id } 
        }
        column_values {
          column {
            id
            title
            settings_str
            type
          }
          text
        }
        updates(page:1) {
          created_at
          text_body
        }
      }
    }
  }

But it returns “This column ID doesn’t exist for the board”

"error_data": {
  "column_id": "connect_boards",
  "board_id": null,
  "error_reason": "store.monday.automation.error.missing_column"
}

How do I know what the column name is that I am supposed to use?

I was able to find in a related post that you can add this to a query to get the columns of the board

  boards(ids: [...]) {
    name
         columns(types: [board_relation]) {
            type
            id
            title
        }
