Where do I put FLAG_IMMUTABLE or FLAG_MUTABLE for Android 12 head?

When I update my Xamarin Android head to compile using Android 12, and change the minimal version to 10.0 and the target to 12.0, I get the following exception when the application starts:

Java.Lang.IllegalArgumentException: '[Package Name]: 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.

The stacktrace is

at android.app.PendingIntent.checkFlags(PendingIntent.java:375)
at android.app.PendingIntent.getBroadcastAsUser(PendingIntent.java:645)
at android.app.PendingIntent.getBroadcast(PendingIntent.java:632)
at androidx.work.impl.utils.ForceStopRunnable.getPendingIntent(ForceStopRunnable.java:196)
at androidx.work.impl.utils.ForceStopRunnable.isForceStopped(ForceStopRunnable.java:128)
at androidx.work.impl.utils.ForceStopRunnable.run(ForceStopRunnable.java:93)
at androidx.work.impl.utils.SerialExecutor$Task.run(SerialExecutor.java:91)
at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
at java.lang.Thread.run(Thread.java:920)

Now my project contains no such PendingIntent so I am wondering what I should do.

In this case adding the Xamarin.AndroidX.Work.Runtime NuGet package did the trick. In general this exception could mean a dependent package is not updated to support this Android 12 requirement.
