Hi Everyone, Using `files_upload` from the SDK Web Client, Is there a way for Slack App to also have a preview for the file uploaded just like a normal user gets when uploading it ?? <img width="430" alt="Screenshot 2021-04-06 at 7 13 08 PM" src="https://user-images.githubusercontent.com/42064744/113720301-215bd400-970c-11eb-8152-17d1be15b5c7.png"> Thanks in advance!
