[FEATURE] Allow file uploads in embedded chat interface

[mhjb]

Describe the feature you'd like In ChatGPT & the OpenAI Assistants Playground, I can upload attachments (where the model supports that) I'd love it if I could do the same with Flowise's embedded chat widget?

Additional context ChatGPT:

Agree, much needed feature. I am working on a chatbot solution where i need to accept images from the user and send these images with users text response over email. Capability of uploading images in Flowise chatUI is much needed.

any update on this?

Also agreed, this is badly needed, and sorely missed. Also option for Text to speech input. Only having it available in share chatbot is missing a trick, thanks @HenryHengZJ for all your incredible work, this platform is by far the best already. Just a couple of tweaks here and there and its the ultimate monster! BUT you are still the AI god! I appreciate you!
