Missing tables – how to recreate?

I have a WP multisite where some of the child sites are missing the *_tec_events and *_tec_occurrences tables. So I’m trying to write a code-snippet to detect when these are missing and re-create the them, since the the-events-calendar plugin is not doing this on plugin activation.

So far I have this code below, but the call is not actually creating the tables: \TEC\Events\Custom_Tables\V1\Schema_Builder\Schema_Builder::class)->up(true)
Any suggestions how I can accomplish my goal of re-creating the missing tables on plugin activation?

  $debug = true;
  $target = 'the-events-calendar/the-events-calendar.php';

  add_action('activated_plugin', function($plugin, $network_activation) use ($debug, $target) {

    if(strcmp($plugin, $target) !== 0) {

      // do nothing

    } else {

      add_action('shutdown', function () use ($debug, $target) {

        $include1 = include (WP_PLUGIN_DIR . '/the-events-calendar/src/Events/Custom_Tables/V1/Models/Event.php');

        $include2 = include (WP_PLUGIN_DIR . '/the-events-calendar/src/Events/Custom_Tables/V1/Models/Occurrence.php');

        if(   !$include1

           || !$include2

           || !class_exists('\TEC\Events\Custom_Tables\V1\Tables\Events')

           || !class_exists('\TEC\Events\Custom_Tables\V1\Tables\Occurrences')

          ) {

          error_log("Failed to find required file or class");

          return;

        }

        $table1 = \TEC\Events\Custom_Tables\V1\Tables\Events::table_name();

        $table2 = \TEC\Events\Custom_Tables\V1\Tables\Occurrences::table_name();

        global $wpdb;

        $count1 = $wpdb->get_var( "SELECT COUNT(*) FROM $table1" );

        $count2 = $wpdb->get_var( "SELECT COUNT(*) FROM $table2" );

        if(!is_numeric($count1) || !is_numeric($count2)) {

          $result = tribe( \TEC\Events\Custom_Tables\V1\Schema_Builder\Schema_Builder::class)->up(true);

        } else {

          // do nothing

        }

      });

    }

  }, 10, 2 );
