Hi, This isn’t the place for Gravity Forms or Divi Support, Only for this plugin. Please contact Divi or Gravity Forms in future.
To add Gravity Forms to Divi, There are a number of ways, Most common is to add a text module and follow the prompts to add a Form,
Alternativly you can add a code module and add the shortcode with the form ID:
[gravityform id=”1″ title=”false” description=”false” ajax=”true”]
