How to send email invitation after google form submit?

Question

JavaScript

There is a google form on the site, it collects the name and mail, using the addon sends a letter with thanks for the subscription.
Tell me how can I embed an invitation to an event in this letter, which can be added by readers?
The scheme is simple for the user - he left contacts, received a letter with thanks and immediately the opportunity to add an event to the calendar.
Difficulty in automation, sending to the calendar requires addressees, but they are not available until they fill out the form.
I see two options:
1. Use some ready-made solution, Google addons.
2. Insert a link to the universal event in the calendar into the letter.
Neither the first nor the second do not understand how to do. If someone is aware of any of the options (or alternative) - share, pluses in karma and all that. :)

Answer 1

the second option is quite normal) you can not only send the event itself, but also with a reminder =)
on the last screen you copy the link and paste it into the letter in any form
