The Attach Document feature allows you to share references and screenshots and add context to messages using the Comment feature within Gutenberg Editor.
Within Inline Comments, contributors can attach media—such as images, screencasts, and audio messages. Extending the use-case of the Google Docs commenting feature, there is no shortage of ways to utilize this collaborative feature.
Attachments may be uploaded directly from your device or within your WordPress media library. These are the accepted file formats for the Attach Document feature:
  • .jpg
  • .png
  • .doc
  • .pdf
