How can I make myself eligible for a Pay-As-You-Go Dev/Test subscription?

Question

I originally created my organization through MS365 for business basic, which created my Azure tenant and AD. I then signed up for Azure itself using my admin account (which I had created with MS365). At the moment, I only have 1 option for a subscription plan: "Microsoft Azure Plan" which I think is the same as what used to just be called "Pay-As-You-Go"? Correct me if I'm wrong please.

It says that I am not eligible for the "Pay-As-You-Go Dev/Test" plan because this offer is for "teams of active Visual Studio subscribers...".

What I want to know is, if I want to have access for my business Azure account to the Dev/Test subscription, under which account would it make the most sense to sign up for a monthly VS subscription? Should I just sign up with the same admin account I used for Azure and MS365 for biz? Because currently, the admin account is the only one allowed on an invoice to create subscriptions. I don't like the idea of adding a standard user account to that. But if I do that, does that lock the VS monthly subscription license to my admin account? I don't want to develop with my admin account. Or can I simply select a different user through I presume the VS portal (or equivalent) to assign the license to? And if I assign the VS license to this different user, can I still create a PAYG Dev/Test subscription via my admin account? Or is the VS licensed user the only one now allowed to make this kind of subscription?

The real confusion stems from if the VS subscription is licensed to a normal user vs. the admin responsible for billing, will the admin now be able to create a PAYG D/T sub, since one of my users has a VS subscription? Or would only the licensed user be able to create PAYG D/T subscriptions?
