The code that you've provided is for repeatable fields and not repeatable field groups.
To display repeatable field groups you will need to create a view. Please follow the instructions in the link below in order to display your repeating fields.
Thank you for the resource link. That was helpful.
I've created a "Health Clearances View" view.
Toolset Shortcodes provided the shortcode [wpv-view name="health-clearances-view"]
When I use that shortcode I'm not seeing any results.
I attached a couple more screenshots hoping that you can see what it is I'm doing incorrectly.
From what I can see you haven't added any content to the health-clearances-view. In your screenshot you can see the Add Block button.
You will need to click on this and add the appropriate blocks that you want to use to display content from your repeatable field group.
In your case I would recommend adding the Single Field block to your view and configuring it to display the correct custom field from your repeatable field group.
