Multipart/form data GET request - Unable to write Postman API

I am working on the frontend (Angular) wherein I want to receive file(s) from the backend (Java/Spring boot) in form of multipart-form data using content-disposition. I have written an HTTP get request in my frontend code to receive and render the file, however I do not have a backend to test my frontend working. I am not able to write a Postman Get request which sends file in the response by using content-disposition.

How do I write a Get Multi-part request to receive the file in frontend by using Postman?
