This is a sample gallery embedded from Airtable (just a proof of concept). You have to copy just the URL out of Airtable’s embed code and use it in H5P.  I didn’t sopend a lot of time adjuting the height and width in H5P-could be better.

It’s useful to be using a theme that allows full width posts! This blog uses the “Spacious” theme.
