Select the SMS number, to be configured for SMS routing, by clicking on it.
Scroll down to the 'Two-way SMS' section and expand the section. Select 'Choose an existing SNS topic'. Select the latest SNS topic created by the Engage CloudFormation stack (it will contain the new stack name as well as 'SMS') and click 'save' at the button of the page.
Note: A new SNS topic will be created each time a dual-stack upgrade is performed. Therefore, after each stack update, this setting must be modified to select the latest SNS topic.
