[Question] Notification and keep personal app state

Hi Trinetra-MSFT,

Thank you for the response. Apologies if my description is not clear to you. So what I wanted to do is to have a customer app where it keep its state. For instance, if I open the custom app and do some operation with it, I want to keep the state of that app and not refresh again if I switch the app to like chat or other apps because usually when I switch apps and open my custom app again, it refreshes the page and it goes back to initial page and all the progress is lost. Another thing is to have a notification with that custom app. For instance, there is an event occurred in the custom application. I want the app to show the notification icon in the app itself, not in the activity feeds because if I'm not mistaken most of the notification goes to the activity feeds but for this application, I want to have it on the custom application. It will show a small notification icon in the custom app icon in the side navigation bar. I hope everything is clear. 

Thank you.
