Meta Query - Elementor

Hi,

I have an Post type for Events, and some custom fields.
Custom field for START DATE and END DATE.
The Start date should be filled, and i have set an toggle for "multi-day" event, so if it say YES, the END DATE field also shows up.

Right now it hide events based on the start date.
But i want to hide events if there is an END DATE - so it should look for this first, and if there is no - it should hide by start date.

Could that be possible?

I have used this code:

/**
 * Update the query to use specific post types.
 *
 * @since 1.0.0
 * @param \WP_Query $query The WordPress query instance.
 */
function my_query_by_post_types( $query ) {
	$query->set( 'post_type', [ 'arrangement' ] );
}
add_action( 'elementor/query/my_custom_filter', 'my_query_by_post_types' );

/**
 * Update the query by specific post meta.
 *
 * @since 1.0.0
 * @param \WP_Query $query The WordPress query instance.
 */
function my_query_by_post_meta( $query ) {

	// Get current meta Query
	$meta_query = $query->get( 'meta_query' );

	// If there is no meta query when this filter runs, it should be initialized as an empty array.
	if ( ! $meta_query ) {
		$meta_query = [];
	}
	

	// Append our meta query
	$meta_query[] = [
		'key' => 'start_dato',
		'value' => date("Y-m-d",time()),
		'compare' => '>=',

	];

	$query->set( 'meta_query', $meta_query );

}
add_action( 'elementor/query/my_custom_filter', 'my_query_by_post_meta' );
