[Harshit Agarwal]

We have below 2 scenarios : - 

1. How to pass custom data in Form Data whenever we are doing file upload.
2. How to create and pass unique id for each file getting uploaded for multiple file upload during chunk upload so that it can be captured in the API and we can write Business logic based on that.
