Welcome to the Q&A Forum

Yes, Dan is correct. As long as the intent is not malicious, you should be good. Moreover, it is a common practice where a JS overlay is displayed before the actual site is served. For example, the adult sites and liquor related websites show an age gate page using JS overlay technique for the human visitors to confirm their age before they can access the website but the search engines bots (like the Google bot) do not see the JS overlay and can directly access the website. With this kind of setup in place, there is nothing to worry about different experience being served to visitors and bots. This is definitely not considered, cloaking. Hope it helps.
