Google Captcha v3 on ChronoForms 7

I just installed Google V3 on my Chronoforms v7 and it seems to work with the Google Logo on the lower right of the site. But as it is hidden (hard to test), I just want to know if you did fully implement it on v7 or is it still under development like I read in other threads ?
V7 is really nice BTW...

it's working!

chronoforms 7 + recaptcha v3 doesn't work for me

Hi Sergey,
​
How is it failing exactly?

I don't understand the reason. Maybe I configured it incorrectly. All attempts to send a message from the site are blocked.
