Can we plan to send a report of its answers to the respondent ?

If you want to send an automatic email response to your users who filled out the form, you can simply set up an autoresponder:

This will automatically send an email to your customer who filled out the form, and it will be sent to their email address that they must provide on your form.

Please take a look at the above linked guide, and don't hesitate asking if you need any further clarifications or assistance. Thank you.
