I can't add any widget or actuators

I am working with ESP8266(wemos d1 mini).My example send temprature data and I can see temprature widget on my dashboard. However I can’t add any new widget or actuator my dashboard like actuator or custom widget. Here custom widget setting look like this.

Here my code:
// This example shows how to connect to Cayenne using an ESP8266 and send/receive sample data.
// Make sure you install the ESP8266 Board Package via the Arduino IDE Board Manager and select the correct ESP8266 board before compiling.

#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.h>
#include <Wire.h>
#include "Adafruit_MCP9808.h"

#define LED LED_BUILTIN  //On board LED
#define ACTUATOR_PIN 4 // Do not use digital pins 0 or 1 since those conflict with the use of Serial.

// WiFi network info.
char ssid[] = "xxxxx";
char wifiPassword[] = "xxxxx";

// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username[] = "xxxxxxx";
char password[] = "xxxxxx";
char clientID[] = "xxxxxx";

unsigned long lastMillis = 0;
// Create the MCP9808 temperature sensor object
Adafruit_MCP9808 tempsensor = Adafruit_MCP9808();

void setup() {
	Cayenne.begin(username, password, clientID, ssid, wifiPassword);

  Serial.println("MCP9808 TEST PROGRAM");
  if (!tempsensor.begin(0x18)) {
    Serial.println("Couldn't find MCP9808! Check your connections and verify the address is correct.");
    while (1);
  Serial.println("Found MCP9808!");
  tempsensor.setResolution(3); // sets the resolution mode of reading, the modes are defined in the table bellow:

  //Onboard LED port Direction output

void loop() {

  if(millis()-lastMillis > 5000) {
    lastMillis = millis();
    tempsensor.wake();   // wake up, ready to read!

    float c = tempsensor.readTempC();
    Serial.print("Temp: "); 
    Serial.print(c, 4); Serial.print("*C\t \n");

// Default function for sending sensor data at intervals to Cayenne.
// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.
	// Write data to Cayenne here. This example just sends the current uptime in milliseconds on virtual channel 0.
	Cayenne.virtualWrite(0, millis());
	// Some examples of other functions you can use to send data.
	//Cayenne.celsiusWrite(1, 22.0);
	//Cayenne.luxWrite(2, 700);
	//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);

  // Write value to turn the relay switch on or off. This code assumes you wire your relay as normally open.
  if (getValue.asInt() == 0) {
    digitalWrite(LED, HIGH);
  else {
    digitalWrite(LED, LOW);

// Default function for processing actuator commands from the Cayenne Dashboard.
// You can also use functions for specific channels, e.g CAYENNE_IN(1) for channel 1 commands.
	CAYENNE_LOG("Channel %u, value %s", request.channel, getValue.asString());
	//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError("Error message");

can you try adding a custom button widget.

Hi @shramik_salgaonkar. Can’t add custom button widget you can see picture of menu on my first comment what is look like.
