Life cycle of foreground service started with setForegroundAsync

Question

In the documentation of setForegroundAsync it says:

"This specifies that WorkRequest is long-running or otherwise important. In this case, WorkManager provides a signal to the operating system that the process should be kept alive, if possible, while this job is running."

But what happens if I run an addProximityAlert like this:

    public Result doWork() {
    setForegroundAsync(createForegroundInfo("Monitorando l'area"));
    
    //...
    
    lm.addProximityAlert(latitude, longitude, radius, -1, pendingIntent);

    return Result.success();
}

Does the foreground service remain active forever? or, is the foreground service killed immediately after running addProximityAlert? if it ends immediately, how can I prevent it?
