Install Script: file url in json file from another url

Hi all, my first post here.

I was just getting myself into the install script editing for the first time and I was wondering if it is possible to get an install file from an url which is inside a json that can be found in a specific url.

The game is Magic The Gathering Arena and It has the latest version on and then the actual file url is inside the json file.

Do you guys knows it the installer scripts support this?
