[CrackBerry Question]

Hello all,
I just switched fro iphone 5s to blackberry passport silver edition (my first blackberry), I installed medscape app from amazon appstore, it was freezing so I decided to uninstall and reinstall it, I hold the icon for few seconds and deleted it from home screen, then tried to reinstall it fro Appstore, but the app was in my amazon app store and I just opened it, but the icon does not come bac to my home screen, I would like to bring back the icon to my home screen but I don't know how to do that, I would appreciate your help.
