How do I add Google reCAPTCHA to my WordPress sign-up form?

Hi,

I'm using the Constant Contact for WordPress plugin, version 2.4.0.

Have v3 reCAPTCHA set up, it's working but some bots are getting through so would like to increase the v3 threshold. But I don't see any place to do that in your plugin. I assume it's using the default 0.5 score.

How can I adjust this?

Thanks,

Ed
