list/consult Taxonomy only for the respective author/creator in dashbboard

I'm trying to filter so that only the creators of the respective categories can edit them. I created a cat_author meta field and associated it to the taxonomy. In this way, every taxonomy has an author. And I tended to filter with

add_filter( 'pre_get_terms', 'filter_cat_by_u_id', 99, 1 );
function filter_cat_by_u_id( $query ) {
    if ( ! is_admin() ) {
      return $query;
    }
    global $pagenow;    
    if ( 'edit-tags.php' === $pagenow ) {
        $meta_query = array(
            array(
                'key' = 'cat_author',
                'value' = get_current_user_id(),
                'compare' = '='
            )
        );
        $query-set( 'meta_query', $meta_query );
    }
    return $query;
}

But I'm not getting a good result. Does anyone have any tips?

UPDATE:

add_filter( 'get_terms_args', 'filter_cat_by_u_id' );
function filter_cat_by_u_id( $args ) {
    global $pagenow;

    if ( is_admin()  'edit-tags.php' === $pagenow ) {
        $args['meta_query'] = array( 
            array(
                'key' = 'cat_author',
                'value' = get_current_user_id(),
                'compare' = '='
            )
        );
    }

    return $args;
}

Thanks to Sally I this solution works perfectly fine to filter the list of custom categories in wp-admin/dahsboar.

The WP_Term_Query class doesn't have a method named set, and calling $query->set() in my case resulted in a fatal/critical error saying "Call to undefined method WP_Term_Query::set()". :/

But you can directly modify the query_vars property (i.e. $query->query_vars), like so, to set, unset or override any query variables like meta_query:

// Use this:
$query->query_vars['meta_query'] = $meta_query;

// NOT this (which causes a fatal error):
$query->set( 'meta_query', $meta_query );

Or you could instead use the get_terms_args hook:

add_filter( 'get_terms_args', 'filter_cat_by_u_id' );
function filter_cat_by_u_id( $args ) {
    global $pagenow;

    if ( is_admin() && 'edit-tags.php' === $pagenow ) {
        $args['meta_query'] = array( your code here );
    }

    return $args;
}
