How to hide wordpress website from public view

I have a WP.org website I either want to password protect (fully every single page) or make coming soon. Based on Google it should be in settings> general or hosting> settings when in wp admin panel, but I don’t have either of these options.

How can I hide the website so nobody can access or see the pages when looking it up or anything, I want it fully hidden but can’t find a way to?
