func handleDecoding<Element: Decodable>(responseData: Data,
                             responseType: Element.Type,
                             completion: @escaping (_ apiResponse: Element?, _ error: String?) -> Void) {
    do {
        let apiResponse = try JSONDecoder().decode(responseType, from: responseData)
        completion(apiResponse, nil)
    } catch {
        completion(nil, "Network Error")
