CastContext.getSharedInstance(Context) is now deprecated

As the title says, CastContext.getSharedInstance(Context) is now deprecated:

getSharedInstance(Context context): This method is deprecated. Use getSharedInstance(Context, Executor) instead to handle the exception when Cast SDK fails to load the internal Cast module. https://developers.google.com/android/reference/com/google/android/gms/cast/framework/CastContext

What would be the correct way to specify an Executor and return the CastContext? I got it working like this but I wonder if this is the best way to do it:

CastContext
    .getSharedInstance(context, Executors.newSingleThreadExecutor())
    .addOnSuccessListener(castContext -> {
        //do something with castContext
    })
    .addOnFailureListener(exception -> {
        //throw exception
    });
