How are made e-mail notifications when table is changed?

Hi, in template Family Todo is used an extension named Notifications. Which one is it? I can’t find how it is done that it sends e-mail.
And what is “Custom Directive”? E.g. used for the Notification extension and a field Expression is “tbd-js-code-editor”.

I tried search throught the forum and documentation and nothing. Thanks.


The Notifications extension is now no longer available and is replaced by the Workflow automation extension Workflow Automation - Tabidoo Help Center. ‘Custom Directive’ is a special data type for internal purposes.
