To add connection, select the arrow next to their name, and then click, Actions, then Add Connection.
Next, select the type of entity you want to add a connection with, then search for the specific entity using the box and select the one you want. After selecting the entity you can optionally add a note about the connection if you'd like.
Once you've saved the connection, the box will change to allow you to add any info fields that are a part of that connection. You can add info by selecting Add Connection Info and then selecting the Field, then response that you want to include.
Once you've added any connection fields you need, you can use the Close button to exit out of the connection box.
