The documentation/example for /samples/GettingStarted/Workflows/Agents/CustomAgentExecutors no longer works.
A missing implementation for ConfigureProtocol is required.
This appears to have replaced the previous ConfigureRoutes method (this was also missing).
Adding an implementation as seen below used to work correctly.

protected override RouteBuilder ConfigureRoutes(RouteBuilder routeBuilder)
{
	return routeBuilder.AddHandler<string, SloganResult>(this.Handle).AddHandler<FeedbackResult, SloganResult>(this.Handle);
}

An attempt to configure the new method inline with the previous ConfigureRoutes does not work.

protected override ProtocolBuilder ConfigureProtocol(ProtocolBuilder protocolBuilder)
{
	protocolBuilder.ConfigureRoutes(routeBuilder => routeBuilder.AddHandler<string, SloganResult>(this.HandleAsync).AddHandler<FeedbackResult, SloganResult>(this.HandleAsync));
	return protocolBuilder;
}

The initial slogan is generated, feedback is provided but no subsequent slogan is attempted.

If it is possible to update this example or provide the details of how the the above method is to be implemented and even if it is associated with the failure to "loop" until the conditions are satisfied that would be great.
