Will Googlebot click a button/link to reveal AJAX content?

my client has to inform it’s customers about some new regulations that the Googlebot should NOT crawl. It is not possible to place this information on a separate page and disallow Google to crawl it. So the idea is to place a button/link on the page, that will AJAX-load the corresponding information only when the user clicks it. My assumption is, that Google is unable to click the link and crawl that specific AJAX content.

Am I right? And if yes, is there an official documentation that proofs my point on this?
