Sending Multipart Requests in mule

Question

I have an Database connector from the selected data i use to create a file and I want to do HTTP post with file (created from the selected data in csv) along with other data (text) as attached in the screenshot. According to the mule documentation, the payload must be an outbound attachment which I am doing by using Set Attachment property. With this approach, I am setting the Content-Type for one of my attachment as application/CVS (as my file is of CVS type) and as text/plain for the other parameter. Any thoughts on achieving this? I have attached the screenshot of how the request looks like in Postman.

Below is the config XML..!!
