Hiding Specific Calendars In The Calendar App

I have been using third party calendar Apps for quite a while now. However, I suppose many Mac people just use the macOS Calendar App, it works pretty well. You may already know this, but you can hide specific calendars (holidays maybe) in the Calendar App. This applies to other third party calendaring Apps as well. This article explains how to hide the Holiday calendar in the macOS Calendar App, but this procedure applies to other specific calendars as well.
