Android “Widget” in Notification Bar (native or cordova)

We try to create an app and would like to show some information for app on notification bar. I don’t know how this is called on android, but some other apps have some widgets in the bar like this


I don’t know howthis is done and how this is called. We can not close the notification and it is still present there. At the end we try to do this with a ionic / cordova app, but if we know how this is done native by android we can google for it and check if there is always a cordova plugin, if we can do this by ionic or if we have to implement this by our own.
