The Google Forms add-on supports dynamic form fields in the email subject and message body. These fields are
                        always enclosed in double curly braces - like {{Your first name}} - and are automatically replaced
                        with the actual answers that the user submits in the form.
To give you an example, if your Google Form has a question titled "What is your name" you can make that a dynamic field by enclosing the question title inside double curly braces as shown below:
{{What is your name}}
These dynamic fields can be placed anywhere in the subject or message body of the email template. The add-on, when sending the email, will replace all such fields using corresponding answers from the form response.
If you enclose a question title from the form inside double curly braces, it becomes a dynamic field. In addition to the question titles of your Google Form, the following variable fields are also available for your email templates.
| Variable Field Title | Description |
