Renaming a theme’s panel’s title in customisation settings

Hi all,

Im creating a child theme for a parent theme. There are some theme customisation settings which the parent theme is generating (so that you can change background colour etc).

The parent theme is creating the panel with

 $wp_customize->add_panel('sparkling_main_options', array(
        'capability' => 'edit_theme_options',
        'theme_supports' => '',
        'title' => __('Sparkling Options', 'sparkling'),
        'description' => __('Panel to update sparkling theme options', 'sparkling'), // Include html tags such as <p>.
        'priority' => 10 // Mixed with top-level-section hierarchy.
    ));

How do I change the title of this panel within my child theme’s functions.php file? I want to change ‘Sparkling Options’ to ‘Advanced Options’.
Thanks
