Description
Current behavior
When a PDF file is shared in a conversation, Rocket.Chat only displays the file name with a download option. There is no visual preview of the document content.
Expected behavior
Similar to apps like WhatsApp or Slack, a PDF attachment should display a thumbnail preview of its first page. Clicking the preview should open or download the PDF.
Why this is useful
- Improves user experience and message readability
- Helps users quickly identify the document content without downloading
- Aligns Rocket.Chat UX with other modern messaging platforms
