Recaptcha version

is wappler using recaptcha v2, v3 or enterprise. I signed up with enterprise and got a site key. It also said that I could get a legacy secret key for 3rd party vendors that haven’t upgraded so I tried putting the secret key in the serverconnect action prior to the send mail step. I put the site key in the contact form. The form shows a white box with error invalid key type. The form does not send as a result. Can you tell me what I’m doing wrong or how to get a legacy site key if there is such a thing to match the secret key.

Thanks,
