 public async Task<APIGatewayProxyResponse> FunctionHandler(APIGatewayProxyRequest apigwProxyEvent,
 ILambdaContext context)
 { 
 // Get SSM Provider instance
 ISsmProvider ssmProvider = ParametersManager.SsmProvider;

 // Retrieve a single parameter
 string? value = await ssmProvider
 .GetAsync("/my/parameter")
