Help! Fetch + QR Scanner

I’ve written code that basically acts as a QR code scanner, currently it opens scanned URLs through an API and opens the URLs in a new browser window showing it’s JSON content.
Problem is, the content shown is basically in the JSON code format where as I’d like to see it as if i’ve used Fetch.

I’ve been trying to use fetch with the QR scanner code but i can’t get it to work.

Does anyone know of an example of a QR scanner that uses fetch to display the JSON URL?

Thanks in advance.
