MeetApp provides a PowerPoint add-in that allows you to include publish dialogue items as well as present charts directly inside your PowerPoint presentation.

To get started using the PowerPoint Add-in open any PowerPoint presentation and select "Insert" -> "Store".

While inside the office store search for "MeetApp" and select to add the MeetApp add-in to your presentation.

After adding the MeetApp add-in you will be asked to login to MeetApp.

When successfully logged in select the event and the dialogue item you want to import (only works with poll types of questions).

After importing the item you can save your presentation and distribute it, no sensitive credentials are stored in the PowerPoint file just an encrypted access token that allows the chart to be rendered in PowerPoint by another user.
