To clarify, do you wish to send an email with the submission data to the person who completed the form?
If so, you will need access to HubSpot workflows, which comes with Marketing Hub Professional and Enterprise. If you're not sure whether you have this tool, please share your Hub ID.
If you would like in-depth assistance in setting up such a workflow, I recommend reaching out to HubSpot support. They can help you 24/7 over the phone, email, and chat, depending on your location.
