We need to extend the Podcast entity so that we can support this. It's not much different than setting up an ACF with the Spotify episode link on WordPress with the embed snippet. Which includes adding podcast episodes to the podcast entity. We will not aggregate the info just yet, but that is a future option.

With the episodes being added to the entity, we will need to capture the Spotify link, and the show notes (from a sanitized WYSIWYG). We'll also include a YouTube URL as well, and embed that video too.

Then, we'll also need to build podcast episode pages on the web app. It's definitely doable, but it's not small.
