NextJS SSG handlers not working on deployed env

Stack: NextJS + Typescript + ChakraUI
Locally it works, deployed, once clicked, it does not work.

Sample:

import { FaPinterestP } from 'react-icons/fa';
...
<FaPinterestP
          size="2.4rem"
          css={socialMediaIcons}
          onClick={() => window.open('https://mail.google.com/', '_blank')}
/>```

How do we see this happen? I believe we should be clicking the Pinterest icon, and that seems to open a Pinterest link in a new tab. Is there something else going on?
