Secret link is not working as per requirement

What I understand from the feature secret Link, is to allow only users with the link to have access to the notebook.

But when I’m changing the access from public to secret, and I’m trying to access it in incognito tab, it is asking me to log in to the jovian account.

When I tried to send the link to the recruiter as secret, they couldn’t access my notebook without logging in. Is there a way to share the notebook link to specific people without other being able to access that?
