Move filesharing UI into Chat box #33
Description
#32 introduced file sharing within a call. That implementation added the fileshare UI as part of the video controls (Controls.tsx), but the ideal design would be to integrate it as part of the Chat box. This means the chat log would also have tha Accept/reject file transfer buttons, as well as a way to share files.
Rationale behind this is that file sharing doesn't fit with the rest of the controls (mute, video mute, screenshare, hangup) and makes more sense as a chat feature. Being part of chat means the context around a file (like why its being sent) is captured as a chat message, followed by the file itself.
