I added a cursor on the chart series, can anyone tell me how to delete it?

Cursor is a very useful feature of chart series (LV_CHART_TYPE_LINE), but I can’t seem to find an API to remove it.
I know that lv_obj_set_style_line_opa can hide all cursors, but if I only want to hide or delete some of them, does anyone have any ideas?

There is not such a function but for version 8.4 you can add this

/**
 * delete a cursor
 * @param chart     pointer to chart object
 * @param cursor     pointer to the cursor
 */
void lv_chart_delete_cursor(lv_obj_t *obj, lv_chart_cursor_t *cursor)
{
	LV_ASSERT_OBJ(obj, MY_CLASS);
	LV_ASSERT_NULL(cursor);

	lv_chart_t *chart = (lv_chart_t *)obj;
	_lv_ll_remove(&chart->cursor_ll, cursor);
	lv_mem_free(cursor);
}
