How can I create custom button in post.php

Use media_buttons action for it. Check below code.

add_action('media_buttons', 'add_my_media_button');
function add_my_media_button(){
 echo '<a href="'.get_site_url().'/wp-admin/customize.php" class="button button-default">Customize</a>';
}

Hope this will helps you.

Thanks!
