In the To Do or Flows I’m In pages, select the Comments tab of an open flow. Simply enter a comment and click Add. The comment will be available for previous, current and future actors on the flow.
To communicate with a colleague: in your comment use the @ symbol and begin typing the name of the user or team that you are directing the comment to; @-mentioning will directly email the user or team and display an app notification.
Any comment will also stay with the flow on which you’ve commented, giving context other users, even after the flow is complete.
Note: When using @-mentioning, they do not need to be an actor on any step of the flow, and will be able to view the flow from then on.
