Just for info,
that’s the code to list events in starting date sort with Elementor Pro Post widget

add_action( 'elementor_pro/posts/query/id_of_the_query', function( $query ){
	$query->set('post_type', 'event');
	$query->set('orderby', '_event_start_date');	
	$query->set('meta_key', '_event_start_date');	 
	$query->set('order', 'ASC');
} );
