How to dynamically reload IOptions<> when another IOptions<> reloads

Question

Imagine the following:

public class FooOptions { 
  public string FooProperty {get; set;}
}

public class BarOptions { 
  public string BarProperty {get; set;}
}

public class ConfigureBarOptions : IConfigureOptions<BarOptions> {
  private readonly IOptionsMonitor<FooOptions> _fooOptionsMonitor;

  public ConfigureBarOptions(IOptionsMonitor<FooOptions> fooOptionsMonitor) {
    _fooOptionsMonitor = fooOptionsMonitor;
  }

  public void Configure(BarOptions options) {
    options.BarProperty = _fooOptionsMonitor.CurrentValue.FooProperty;
  }
}

// in Startup.cs - bind to a configuration provider that is set to reload
services.Configure<FooOptions>(Configuration);

How can I trigger a reload of BarOptions when FooOptions is reloaded due to an underlying configuration update?

I've played around with various attempts at registering some versions of:

services.AddSingleton<IOptionsChangeTokenSource<BarOptions>>(new ConfigurationChangeTokenSource<BarOptions>(name, config));

I've also tried to think of a way to use ChangeToken or _fooOptionsMonitor.OnChange but haven't seemed to get the right implementation.
