When I try to create a function app, the Hosting tab is missing

Question

I have a free basic subscription.

I am trying to create a function app for learning PnP Provisioning Engine. When I try to create the Function App, all the online guides say there should be a tab for Hosting where I need to select my Storage Account (or create a new one) looking like this

When I do it that tab is missing like this

If I do the same on a MSDN subscription then its there fine. I cant find anything online saying I need a special type of subscription to see this. If I create one without it then it won't let me upload my .pfx certificate which I am thinking is because there's no storage account connected to load it into
