The following example shows how to stop observing the “gpu” source after the observer previously observed both, the “cpu” and “gpu” sources.

const observer = new PressureObserver(callback);

observer.observe("cpu");
observer.observe("gpu");

// Callback now gets called whenever the pressure state changes for 'cpu' or 'gpu'.

observer.unobserve("gpu");

// Callback now only gets called whenever the pressure state changes for 'cpu'.
