Not Exporting Customizer Setting

Hi, the plugin does not export customizer setting and if I use the below code….

add_action(‘advanced_export_all_options’,’prefix_add_all_options’);
function prefix_add_all_options(){
return true;
}

…then when imported, it also changes the siteURL and homeURL, passwords and email as well.

How to only export the customizer settings like colors set, font-selected, container width etc.
