The contact is referenced by its Record ID property, which might change e.g. during data migration to a new device.
Once the contact has been updated, the first output is triggered.
If there is an error, the second output is triggered.
On Android, there are a few outstanding bugs:
Custom labels get overwritten to "Other",
Postal addresses cannot be upated.
Phone numbers and emails are inserted instead of updated.
If the user hasn't given permission to access contacts, they will be requested automatically.
