Does anybody use google recaptch enterprize for detect leaked credentials?

I did everything like described here

https://cloud.google.com/recaptcha-enterprise/docs/check-passwords#:~:text=Set%20up%20reCAPTCHA.,Google%20Cloud%20project%20billing%20ID.

But after one year of checking credentials in live system there was no any leak detected.

Maybe I did something wrong, please share your expiriance.
