Post-installation instructions – Can’t “View Details”

Hello,

I am starting a new site, and have installed and activated the WP RSS Feed Retriever plugin.

The instruction video indicates that, to add a new feed to a page using Gutenberg, to click “View Details” for an example shortcode, copy that shortcode, and paste into a page.

On my site (hosted at Siteground) – when I click View Details, the details area is blank. This happens on all of my Siteground sites. I don’t think it’s a bug in this plugin, but something odd happening at Siteground.

I would still like to try the instructions from the video, so I want to find the shortcode so I can copy it.

Question: Is there another location, maybe on the main website, where I can copy the shortcode?

Your help is much appreciated.
