Crash for android version S: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

I got this issue after upgrate targetSdkVersion to 31, i use this dapendency

implementation ('com.facebook.android:audience-network-sdk:5.5.0'){
        exclude group: 'com.google.android.gms'
    }

and i initialized my apps with this snippet code in Application class

private fun defaultProcessInitialization(app: NewsApplication?) {
        if (BuildConfig.DEBUG) {
            StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder()
                    .detectAll()
                    .penaltyLog()
                    .build())
            StrictMode.setVmPolicy(StrictMode.VmPolicy.Builder()
                    .detectAll()
                    .penaltyLog()
                    .build())
        }
        // Let Audience Network SDK know that you want to use Multiprocess Support
        AdSettings.setMultiprocessSupportMode(
                AdSettings.MultiprocessSupportMode.MULTIPROCESS_SUPPORT_MODE_ON)

        if(BuildConfig.DEBUG){
            AdSettings.addTestDevice("xxxxx")
        }

        AudienceNetworkAds
                .buildInitSettings(app)
                .withInitListener(app)
                .initialize()
    }

Fatal Exception: java.lang.IllegalArgumentException: mobile.android.tribun: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.
