Pay What You Want for Digital Download Products

Hello All.
I am hoping someone can get me started in the right direction.

I am wanting to have digital download product store be pay what you want...$0, or whatever. Having preset values won't work for me in this instance.

I am using Stripe as my payment processor, and from their end, I can create payment links for "Customers pay what they want" and integrate that code.

However, what I would like to do, is in the Squarespace store, have the SS manage the digital download purchase stream...storing the file, emailing it to the customer, providing the download link, etc.  I am not clear how this is possible. A Donation block is not something that will integrate in a seamless purchasing process, from my research and testing.

So overall, my goal is:

• Digital Product Store hosted on squarespace.
• Squarespace manages the digital file access/download links
• The customer can load as many digital products in their cart and choose how much they want to pay for each of them
• If they pay $0, they don't have to enter a credit card

Any thoughts on what am looking at for this implementation would be really appreciated.
