figured it out.

/*
* Update last activity for a user
*/
add_action( 'init', 'update_session_activity' );
function update_session_activity() {
    if ( is_user_logged_in() ) {
        $manager = WP_Session_Tokens::get_instance( get_current_user_id() );
        $token = wp_get_session_token();
        $current_user_session = $manager->get( $token );

        // update last activity to current server time
        $current_user_session['last_activity'] = time();

        // update current session with new activity time
        $manager->update($token, $current_user_session);
    }
}

Awesome, thanks!

Any idea what the best approach for renaming “Product(s)” to “Game(s)” would be? Do I need to change every value in the language files? If so, was not quite sure where the files should go to not get over-written on plugin update.
