rate limiting is not working for with .net6 and AspNetCoreRateLimit 5.0

I'm trying to setup rate limiting for my app but unfortunately it's not working as expected. In the below example, I've setup a limit to 1 under 1 min. But, I'm able to make multiple requests to the API's wthin the timeframe.

Here is my startup.cs file


builder.Services.AddOptions();

// needed to store rate limit counters and ip rules
builder.Services.AddMemoryCache();

//load general configuration from appsettings.json
builder.Services.Configure<ClientRateLimitOptions>(builder.Configuration.GetSection("ClientRateLimiting"));
builder.Services.AddMemoryCache();
builder.Services.AddInMemoryRateLimiting();

// Add framework Services.
builder.Services.AddMvc(option => option.EnableEndpointRouting = false);

// configuration (resolvers, counter key builders)
builder.Services.AddSingleton<IRateLimitConfiguration, RateLimitConfiguration>();

var app = builder.Build();
app.UseClientRateLimiting();
app.UseMvc();
await app.RunAsync();

and here is my appsettings.json file

{
  "ClientRateLimiting": {
    "EnableEndpointRateLimiting": false,
    "StackBlockedRequests": false,
    "ClientIdHeader": "X-ClientId",
    "HttpStatusCode": 429,
    "GeneralRules": [
      {
        "Endpoint": "*",
        "Period": "1m",
        "Limit": 1
      }
    ]
  }
}

I've looked on stack overflow and googled a bit but couldn't find anything helpful.
