extend members account with information gathered from azure function

as part of my store I’d like to extend the members area with details of the items they purchased. these aren’t stored in Shopify, we have a post checkout process which allocates items from a randomised table.

so the specific use case i need is to extend the members area with a purchases section, in which i can add specific ID’s for each of the purposes.

Is this a snippet? or an embedded App?

I cant quite tell from the documentation. If anyone sees it, let me know before i go digging into the App documentation. if feels like an embedded app as its going to need to call the azure function, then present the information that comes back.
