Personalized digital product (video + sound clip)

Hello everyone, I would appreciate your help. I set up a personalized digital product store (video + sound clip).
my question is :Is there an existing digital product application that is not automatically downloaded after purchase?

I will explain the process during and after purchase that I want to implement:

  • Order a video (add a person’s name)
  • Go to purchase and make a payment.
  • The order goes to my processing process (creating a video and a sound clip)
  • After the video is ready, I want to upload it to the application and send the client a message to download it.
  • After downloading, get an indication that the customer has downloaded the video.

technical details:
The video is not automatically downloaded only after I prepare it and upload it to the application.

  • The video is 50 mg.

I would appreciate your help .
