Can Pinpoint send a notification-message?

I am currently developing an app using React Native. For the management screen, I am using Laravel and creating campaigns on Amazon Pinpoint through createCampaign of aws-sdk for PHP to deliver push notifications for both iOS and Android. At this point, I was able to display push notifications as banners successfully. However, I noticed that push notifications could not be received after killing the Android app. This also applies when the app is restarted and placed in the foreground. I have researched and found out that there are types of FCM push notifications that can be received when the app is killed and some that cannot. Is it impossible to send notification messages that can be received even after the app is killed via Pinpoint? I apologize for my amateur knowledge and poor expression, and would appreciate any help or wisdom.
