Protector stack layers a transparent GIF image over the content. So when you are clicking the content, you are actually clicking the GIF image and not the visible content layered underneath.
I discontinued Protector stack because few people used it and it doesn’t stop someone just screen grabbing the content or getting to it via the page source code. But the same protection method still remains an option in ImageWizard, for induvidual photographs.
In all honesty, back to the OP question, disabling right-click (or similar functionality) is a really dangerous and stupid thing to do in public facing websites. A lot of Internet Explorer and Edge users on Windows right-click to navigate within a page or back to the previous page - so removing this ability will land you with numerous complaints that your website is “broken”.
Additionally there are probably legal issues at stake, if a disabled person arriving at your website is blocked from right-clicking a block of content and having their screen reader software read it aloud. Don’t underestimate how many people use assistive technologies for web browsing - and this includes simple tools like double clicking or tapping to change text sizes.
If you are that concerned about people copying your content, then either don’t publish it online to begin with or put it behind a paywall / firewall and require membership access to view it.
