How to modify list of events in backend (admin) of The Events Calendar plugin?

Okay, I found the solution myself.
I used the WordPress hook parse_query. This is the most precise thing I found.
And in this hook I check if it is backend and my user has his meta data called “organizer_id” which I added earlier. But it is only to get the needed organizer_id for filtering the list.

Here’s the code:

add_filter( 'parse_query', 'ozz_filter_events_by_organizer' );
function ozz_filter_events_by_organizer( $query ) {
    $current_user = wp_get_current_user();
    $organizer_id = get_user_meta( $current_user->ID, 'organizer_id' );

    if ( is_admin() and $query->query['post_type'] == 'tribe_events' and !empty( $organizer_id ) ) {
        $qv = &$query->query_vars;
        $qv['meta_query'][] = array(
            'field' => '_EventOrganizerID',
            'value' => $organizer_id
        );

        //echo '<pre>' . print_r( $qv, true ) . '</pre>';
    }
}

So this filter-hook fires each time there is a query on the site. Not very handy but best I could find. So it allowed me to filter the query when it considered particularly the event list in the backend.
