Change SMS content

To change the content of the default SMS templates, you can override the getContent function in the smsDelivery object. It allows you to return an object that has the following properties:

body: This is the email's body. This can be HTML or just text as well.
toPhoneNumber: The phone number where the SMS will be sent to.
