Allow uploading PDF to a chat on mobile Messenger (SDK)

That’s a feature I’ve been requesting for years. I move from one company to another, but the feature is still not there. Please, prioritise.

We need a way for customers to send us PDF via chat. As a financial mobile app, we need to collect various documents from each of our customers. So 100% of our users are facing this problem. The only way to contact us is via in-app mobile chat (Intercom Messenger SDK). We don’t have any web-version. 

Please, allow submitting PDFs and potentially other files on mobile SDK, like you allow doing it for all the rest channels.
