Help Needed: Automating PDF Workflow in n8n/Make Dust Node

Hello I am facing problem with the n8n/make dust node. I am not a tech, and i am trying to create a workflow with a trigger (email or whatsapp) when a message is received with an attached document (pdf), the document is transferred to my agent into dust to analyze it and give me a response. Actually I'm doing it manually by copy-pasting the content of the mail and uploading the pdf files in the conversation with my agent Does someone have done that before ? Thank for your help !
