Hi I’m new to Polly v8.
I have an API client class built using _client = new RestSharp.RestClient(...); with methods of this form:

public async Task<TResponse> PostAsync<TRequest, TResponse>(string resource, TRequest payload) where TRequest : class
{
    var request = new RestRequest(resource);
    request.AddJsonBody(payload);
    var response = await _client.ExecuteAsync<B2BResponse<TResponse>>(request, Method.Post);
    LogAndRaiseErrors(request, response);
    return response.Data.Data;
}

Here’s the LogAndRaiseErrors method:

protected void LogAndRaiseErrors(RestRequest request, RestResponse response)
{
    if (response.StatusCode != HttpStatusCode.OK)
    {
        _logger.LogError("API Error:{response}", SerializeResponse(response));
        throw new BigCommerceException(response.Content);
    }
    _logger.LogDebug("B2B API Call:n{response}", SerializeResponse(response));
} 

I’ve had a look at the Polly documentation, but it is a bit sparse.
How would I construct a ResiliencePipeline and use it in the PostAsync method to achieve the following goals:

• Log every request (currently done in LogAndRaiseErrorsMethod)
• Read the response.Headers.FirstOrDefault(h=>h.Name?.ToLower() == "retry-after")?.Value and delay for the specified seconds, which the existing code does not do at all.
• Log when retries occur including the delay specified in the header.
• Move the LogAndRaiseErrors(...) into the Policy so the policy can deal with logging and any exceptions
• Add Policy to retry for network failures/timeouts etc.
