Need easy simple steps for reCAPTCHA Enterprise

I thought it was just me, but I have implemented reCAPTCHA Enterprise on many wordpress websites but there is one in particular which stays with an 'imcomplete' status, I have done the same steps on all, but this one requires the coding instrucctions for the backend which to me are the same as if they were in a alien language. Is there a simple way to know what to do? Like: "put this code between these lines in this file", or "create this file with this and place it this route" and you're done!

I am stuck on the backend step "Send tokens and get scores (Backend)" and I get this message:
"Finish setting up your key: Request scores

To fully protect your site or app, finish setting up your key. Your key is requesting tokens (executes), but isn't requesting scores (assessments)."

Some one please help me.
