Google recaptcha doesn’t work

Hello, I have correctly integrated google recaptcha v3 to contact form 7. However, it doesn’t work. I receive tons of spam to my e-mail account. There is no error on console, according to contact form 7, so I don’t know, what could be wrong.
That’re the messages I received: https://prnt.sc/uesbls
Here’s the link for CF page: https://kvitok.sk/kontakt-predajne-miesta/

Could you please check, what can be wrong?

The version of CF7 plugin is 5.0, I have no upgrade notice in my dashboard for that plugin.
