In a plugin I’ve this filter

// Let the extensions add any menu earlier than motion buttons.
            $extended_tab_listings = apply_filters('rm_after_front_tabtitle_listing',array()); 
            foreach($extended_tab_listings as $tab){ ?>
                <div class="rmtabs_head <?php echo $tab['class']; ?> rmtabs_head" title="<?php echo $tab['label'] ?>" data-rmt-tabcontent="#<?php echo $tab['id'] ?>"><?php echo $tab['icon'].' '.$tab['label'] ?></a></div>
            <?php }
            ?>

I’ve tried passing the array to the filter as follows, by amalgamating; Utilizing multi-dimensional array with filter and https://pippinsplugins.com/a-quick-introduction-to-using-filters/. Nevertheless, it’s not working appropriately.

operate nj_add_rm_after_front_tabtitle_listing() {
    // Add the titles of tabs we would like

    $array = 
    array( 
        'label' => "TEST",       
        'class' => "my-class",    
        'icon' => 'my-icon',   
        'id'  => '123',  
    );

    return $array;
}
add_filter('rm_after_front_tabtitle_listing', 'nj_add_rm_after_front_tabtitle_listing');

What’s the appropriate methodology to move the variables?
