OneSignal: Show message in a device with app closed (firebase login)

Hi guys,

How Can I show a message in a device that the app are closing?

I’m login with firebase, but the app are closing (if me reopen the app, dont need enter credentials beacause i’am login with firebase)

Thx

Nothing have the same problem? When the app are opened, run correctly, but if i closed the app, don’t show messages
