Are there any guides illustrating how to integrate Page Speed Isights with reCaptch v3?

First question, should my API validate the captcha token before calling PSI?

Second question, what should my site do if PSI returns a sort of error response from the supplied captcha token like CAPTCHA_NEEDED?

I'm using next-recaptcha-v3 on the frontend. Beyond some basic documentation, there's nothing outlining the full integration that I have found.
