Adding a <script> to the content editor most likely won’t work due to the way the WP editor strips out some content. Have you tried adding it to a widget?
I’m not sure about the shortcode as I have no knowledge of how it’s build and what’s supposed to output from it.
It looks like you’re just using a regular page, so GP isn’t doing anything special like it would on a page with Sections for example – it’s just using straight WP core to display the content.
