As an EmbeddedChat developer

I need to:
add options in the starred files list and pinned files list to unstar, unpin, copy the link to a message, along with the provided navigate to that message option

So That:
users can efficiently manage starred and pinned files while maintaining seamless access to the associated messages.

Acceptance Criteria

• Users can click an option to unstar a file from the starred files list, and the file is immediately removed from the list.
• Users can click an option to unpin a file from the pinned files list, and the file is immediately removed from the list.
• Users can copy the direct link to the message associated with a starred or pinned file. The link should be ready for sharing
