I try to change a subitem with this query:

buildEditSubItemQuery(
    boardId: number,
    itemId: string,
    subItemId: string,
    columnValues: object
  ): string {
    return `mutation {change_multiple_column_values(item_id: "${itemId}", board_id: ${boardId}, subitem_id: ${subItemId}, column_values: "${JSON.stringify(columnValues)}") {id}}`;
  }

but the change_multiple_column_values don´t recognize subitem_id, someone can help me to find the correcly function for change columns in subitems?
