How to verify domain for Google recaptcha v3

I'm trying to use Google ReCaptcha V3 for my site, but when I load the page always get a message "Invalid site key or not loaded in api.js".

So for the first question, I need to make sure Google Recaptcha V3 can run on the local environment, right? (without SSL)

If it can run, How to verify domain or site key is correct?

Please help me :)
