About trigger fields
Trigger Fields are the fields used for setting up an action in the admin user interface.
Creating your first trigger field
In order to create your own Trigger_Field you need to extend Thrive\Automator\Items\Trigger_Field and implement the required basic methods.
﻿abstract public static function get_id(): string - should return a unique identifier that will be used as a key in arrays. To avoid conflicts or overwrites we suggest using a prefix.
