You get the URL to download the data in the JSONL format in response to your https://help.shopify.com/en/api/graphql-admin-api/reference/mutation/bulkoperationrunquery, BulkOperation.url
Nope, that is the graphql URL to the BulkOperation object. So you just need to query that object, specifically its "url" attribute, which should be an HTTPs based URL resource.
