Migration from Polly to Microsoft.Extensions.Http.Resilience - Extend ShouldHandle

I want to migrate from Polly to the Microsoft.Extensions.Http.ResilienceAddStandardResilienceHandler. My shortened Polly code is the following:

services.AddHttpClient<MyService>()    .AddPolicyHandler((_, _) =>    {        return HttpPolicyExtensions.HandleTransientHttpError()            .Or<HttpRequestException>(exception => exception.StatusCode == HttpStatusCode.Conflict)            .WaitAndRetryAsync(3, sleepDurationProvider: i => TimeSpan.FromSeconds(i * 2));    });

The crucial part here is HttpPolicyExtensions.HandleTransientHttpError().Or<HttpRequestException>(exception => exception.StatusCode == HttpStatusCode.Conflict) where I want to add a custom error case in which I want to do a retry.

I do not really know how to convert this into the new configuration.

As far as I understand the docs I can set a custom options.Retry.ShouldHandle function (Gets or sets a predicate that determines whether the retry should be executed for a given outcome.)

But then I cannot add a case rather than I have to set the whole function. Microsofts default implementation of ShouldHandle looks like this:

public static readonly Func<TArgs, ValueTask<bool>> HandleOutcome = args => args.Outcome.Exception switch{    OperationCanceledException => PredicateResult.False(),    Exception => PredicateResult.True(),    _ => PredicateResult.False()};

My current config looks like this:

services.AddHttpClient<MyService>()    .AddStandardResilienceHandler()    .Configure((options, _) =>    {        options.Retry.ShouldHandle = args =>        {            if (args.Outcome.Result?.StatusCode == HttpStatusCode.Conflict)            {                return PredicateResult.True();            }            return args.Outcome.Exception switch            {                OperationCanceledException => PredicateResult.False(),                not null => PredicateResult.True(),                _ => PredicateResult.False()            };        };    });

Is this equivalent to the initial Polly implementation?
