The Contacts Section allows you to control the two particular items in the Interactive View Contact Action Bar.
The “Show Opportunities Icon in the Contact Action Bar” option allows you to view the opportunities for that contact. To make this work, you need to make sure you have your Infusionsoft Account setup with the API Key.
Note, if you use the “Show Contacts Action Bar” option it will make all the action bars appear on the page. This may make it confusion on which contact record it belongs to.
