I am trying to implement reCaptcha in LWC. 
I only complete example I find is here in the blog post 
Blog Post (https://www.learnexperiencecloud.com/s/article/Implementing-reCAPTCHA-in-Community-Cloud). 

Now my question is where do we expose the site key in LWC. 
If someone can guide me with an example for implementation of any version of reCaptcha in LWC that would be helpful.
