Hello, I'd like for my chatbot to let users upload a PDF document for summarisation. I asked the chatbot on the Botpress site, but the answer was that Botpress does support this, but it doesn't actually say how. Here's what I'd like the bot to do: * Have an "upload" button * The user can upload a document * The bot would summarise it (it's fine if it needs a 3rd party integration, I'd need to know which supported 3rd party tool to use for this) Any help would be super appreciated -- thanks!

it would inersting to be able to post a file or and audio
