The Google Forms notification add-on is available as a free download for all Gmail and G Suite accounts.  The basic features are free but you can upgrade to premium for more features.

Please note that the license is per Google account (not per form) and you only need a single license for all Google Forms in your account. Also, the license is only required by the form owner and not the form respondents.
