Uso de ListUserPools con un SDK de AWS o la CLI

    /// <summary>
    /// List the Amazon Cognito user pools for an account.
    /// </summary>
    /// <returns>A list of UserPoolDescriptionType objects.</returns>
    public async Task<List<UserPoolDescriptionType>> ListUserPoolsAsync()
    {
        var userPools = new List<UserPoolDescriptionType>();

        var userPoolsPaginator = _cognitoService.Paginators.ListUserPools(new ListUserPoolsRequest());

        await foreach (var response in userPoolsPaginator.Responses)
        {
            userPools.AddRange(response.UserPools);
        }

        return userPools;
