Hey there! I'm trying to upload media files to Twilio in order to use them in conversation messages, as described there: https://www.twilio.com/docs/conversations/media-support-conversations#sending-a-media-message

It works well from Postman when I manually upload a file in the Postman UI. However, I'm trying to make it possible from my backend, using file URLs that are generated from my file manager.

• On Postman, I have have tried doing like that (https://ibb.co/5ktn2k0) but it seems that the file is not recognized - I get a response with "content_type": "application/octet-stream", and I can't use the response to send in conversation messages.

• Also, in my backend, I have tried this (https://github.com/TwilioDevEd/api-snippets/blob/master/conversations/send-media/sendMedia.js) but the error says that the fuction prepareMessage() is doens't exist on conversation

Can anyone help? Thanks a lot!
