"type" is missing from security definition

Having this code with security setting:

    services.AddOpenApiDocument((configure, provider) =>
          {
              configure.Title = name;
              configure.Description = name;
              configure.Version = "1.0.0";
              configure.UseControllerSummaryAsTagDescription = true;
              configure.AddSecurity("oauth2", new OpenApiSecurityScheme
              {
                  Name = "Authorization",
                  Type = OpenApiSecuritySchemeType.ApiKey,
                  Description = "The Identity Server will return an access token; this should be added to every request, using the Authorization header with the Bearer scheme.",
                  In = OpenApiSecurityApiKeyLocation.Header,
                  ExtensionData = new Dictionary<string, object>
                  {
                      { "x-amazon-apigateway-authtype", "cognito_user_pools" },
                      {
                          "x-amazon-apigateway-authorizer", new Dictionary<string, object> {
                              { "providerARNs", new []{ "${user_pool_arn}" } },
                              { "identitySource", "method.request.header.Authorization" },
                              { "type" , "cognito_user_pools" },
                          }
                      },
                  },
                });
    });

Results in such open api file:

securitySchemes:
  oauth2:
    type: apiKey
    description: The Identity Server will return an access token; this should be added to every request, using the Authorization header with the Bearer scheme.
    name: Authorization
    in: header
    x-amazon-apigateway-authtype: cognito_user_pools
    x-amazon-apigateway-authorizer:
      providerARNs:
      - ${user_pool_arn}
      identitySource: method.request.header.Authorization

i wonder why { "type" , "cognito_user_pools" } is missing from api scec? it is required field for aws api gw.
