Create item with multiple column values

In the api documentation of Monday it is said that to add an item, we can use this GraphQL line:
mutation {
create_item (board_id: 1234567890, group_id: “group_one”, item_name: “new item”, column_values: “{"date":"2023-05-25"}”) {

What do we have to add to this line to create an item with multiple column values ?
Best regards,
