Are you making the request via a REST query or with something like fetch in a JavaScript query? Typically I'd recommend using a REST query but that would cause the request to pass through the Retool backend which would cause it to hit the 50MB restriction. Using JS lets the request happen directly from a sandboxed environment in the browser which can be a workaround, Bradly has a detailed post that implements this strategy here. It's no longer needed for S3 and GCS but I imagine it can still work for Azure.
