I want to open app(ionic5) is killed/closed with notification-data.

json for api fcm-google is below:

{
"to": "ca2KNRcxSz2waPUzY1SogM:APA91bH1hopX7x55urxeubs4Y0UQvYAoQtMaciLymjSxN0ht9AshWwXo4fkXpKmASHjyCG2Q8B8pw0X_0PtgfKByWVRPV2ARVQ85OWK8q06XZkYxAeLhIZvpISab9CemfU47CW5IagVE",
"data": {
    "force-start": "1",
    "forceStart":"1",
    "no-cache": "1",
    "body": "Test",
    "title": "Test",
    "sound": "default",

There is not sufficient information in your issue to diagnose any specific problem - you didn't even say which platform this relates to (iOS or Android).
However, based on your reference to force-start I presume you are referring to what is not a standard Firebase feature but is specific to phonegap-plugin-push which uses it to trigger an intent if the app is not already running on Android.

This plugin does not yet contain such equivalent functionality, however this is an open issue (#235) to integrate the AutoStarter library for Android to resolve this.
