 Instead of a post-processing dialog, you can implement a task pane to open after a user reports a message. For example, you can use the task pane to show additional information based on the user's input in the preprocessing dialog. Similar to the post-processing dialog, the task pane is implemented through the add-in's `event.completed` call.
