Describe the bug / error

The new modern ui for document libraries provides access to the "chat function" (known from lists). Unfortunately, this chat seems only partly implemented and buggy.

For files:

• Text messages can be added
• @mentions are broken (placeholder for mention in text and no email sent to mentioned person)
• no indication of chat in grid (chat icon next to three dot menu of item).

Show screenshots

For document sets:

• chat doesn't work at all (error message appears)

Show screenshots

Steps to reproduce

1. Create a document library (optionally, with document sets)
2. Add a new file (optionally, a new document set)
3. Access properties of file or document set
   a) via three dot menu (properties)
   b) via custom json formatting

"customRowAction": {
    "action": "editProps"
}

5. Add text or text with @mention to the chat box and press sent button.

Expected behavior

1. Chat function shall work without error for files and document sets.
2. Emails shall be sent if @mentions are used. Mentioned persons shall be shown in chat messages (instead of placeholder).
3. Chat icon should be visible in files grid (in addition to three dot menu, like available for sharepoint lists, see screenshot below).
