How to upload a file to Hasura Engine and pass it to azure blob storage Action without using Base64?

### Version Information
Server Version: 2.37.0

### What is the current behaviour?
I'm using Azure serverless functions with storage blob accounts, I wanna make a functions that will be responsible for uploading files coming from Hausra to azure storage... but I don't wanna use base64 cause of its cost!

### What is the expected behaviour?
Upload a blob file to Hasura Action and upload it to blob storage accounts using FormData not base64

Start with the Hasura Actions documentation and the Azure serverless-function upload flow described in the issue. Check how Action inputs are transported and how Azure Blob Storage accepts them; done means establishing whether FormData can replace Base64 and documenting the supported behavior or required scope.
