Automatically detect new versions of app

Hi, I’m trying to release my first ionic app. I want to know how users get to know that there is a new update in PlayStore and how do they download it ?

What is the Ionic Native App Update (https://ionicframework.com/docs/native/app-update/) ?

And is it enough to increase the version no in config.xml when app build for a new updated release?
