I have installed the pro version, however when I view the settings I do not see contact form 7 appearing as an option?

Yes, that is how to manually add the code to the contact page.
According to the following list the contact form7 should appear as a tick box on the list (see below)

CF7 forms are little different then other forms. Other forms are only 1 form per type. But a website can have multiple CF7 forms. So user can activate captcha per form by adding that code in the form. Also as this captcha support multiple types (v2 & v3), User can show captcha where they want by this method. A tickbox will not have that much flexibility.
