When using the Send Message API endpoint (https://services.leadconnectorhq.com/conversations/messages) to send emails with a PDF attachment, the file gets attached successfully — but it always appears as “attached file” with no name or extension.

When recipients download it, the file still shows up as “attached file”, which can be confusing for non-technical users who may not know they need to rename it to open it properly.

It would be great if the API allowed specifying a custom file name and extension (e.g., invoice.pdf) when sending attachments, or automatically used the original file name of the uploaded PDF.
