Sitemap for Dynamically Generated Content

I’m currently using the Airpress plugin, which dynamically generates virtual posts, by connecting to an airtable database, in my case, to display products. Wondering what the best way to get this dynamically generated content, which doesnt exist within the wordpress database, into my sitemaps and indexed. I’ve tried searching around quite a bit and have found a few manual/external possibilities, but would love some direction on getting this functional while still using Yoast. Thanks in advance ??
