Thanks for writing in! Because what you are trying to accomplish requires a template customization, we would highly to suggest that you use a child theme. This allows you to make code changes that won’t be overwritten when an X update is released.
After the child theme is set up, please add the following code in your child theme’s functions.php file
echo do_shortcode('[cs_gb id=123]');
And just make sure that you have replace
[cs_gb id=123] with the correct global block shortcode.
Hope this helps. Please let us know how it goes.
