You will first have to be an Admin. If you are not an Admin, then please contact your Building Admin to make changes in Intercom Directory.
Go to Intercom Settings:
Click "Edit" by the Intercom Directory entry that you want to edit:
You can make changes to the entry by adding Intercom Recipients or you can make changes to the Display Name by selecting the "Custom" option and then editing the entry.
Once you have made your edits, click the purple "Save" button. Then you should see the edits of the entry reflected on the SwiftReader instantly.
