Getting started with Site Settings and Gutenberg

Hi,

I've been searching everywhere for help with this but can't find anything.

I have a site settings page that I created. It works fine in the beaver builder framework.

I am working to switch to Gutenberg editor. I can't seem to get the site settings to pull into the page when I add a shortcode. In fact, I've tried many attempts to use shortcodes without any success.

The shortcodes work really easily in beaver builder. Of course I've used the Metabox help page on shortcodes, but nothing worked. https://docs.metabox.io/shortcode/

Can you point me in the right direction on how to implement the shortcodes for the site settings?

Thanks,
Eric
