Google Api - need IP address range for my bubble.io

Installing Google APi and keys, and trying to strict to my web site, but google is saying I need the IP range rather than limiting to the web site.

How do I find my bubble.io IP range, I dont have a dedicated IP

Thanks in advance

It is not possible to have an IP address range.. limit it using the domain.. If you have difficulties bubble bot will guide you great in setting up everything
