A new Chat feature is coming to Google Drive for BergApps users.
Beginning on May 7, Google will be rolling out this feature to your BergApps (Google Apps) account. Chat in Docs and Slides has a new look similar to what you’re used to in Gmail. You can now start a group chat with just one click. Simply select the new chat button at the top right and a chat box will appear, making it easy for you to quickly message everyone who is in the file.
