HTTP Request - Binary Body Format

Hi
I want to attach a zip file using API. TO do this I need a zip file in binary format. This is how it looks in Postman

I tried to convert file using: Convert.ToBase64String(File.ReadAllBytes (“FilePath”))

And pass it in Options of HTTP Request:
Body: FileText
Body Format: “application/binary”

Do you know how to do this in UiPath?

Kind regards
