cannot convert 'esp_interface_t' to 'wifi_interface_t'

Your Code that I edit for ESP32 only and I try Verify .. and it will error at this line _"esp_wifi_set_mac(ESP_IF_WIFIAP, &GatewayMac[0]);"

define SKETCH_NAME "ESP-NOW GATEWAY"

define SKETCH_VERSION "2022-01-01"

define SKETCH_ABOUT "ESP-Now Gateway template code and demonstrator of simultaneous ESP-Now and WiFi."

/*

• This is a template code for an ESP-Now Gateway for ESP8266 and ESP32. It assumes Arduino IDE.
• Note. ESP8266 and ESP32 use different WiFi implementations why you must set the appropriate

• define USE_ESP8266 or USE_ESP32. Please remember to also set the appropriate BOARD in the

• ARDUINO IDE to find the correct include files.
• The Gateway receives messages on the Espressif proprietary protocol ESP-Now. It also provides a simple WEB server
• displaying the received temperature data from all sensors. This is to demonstrate a single ESP8266 is capable of
• communicating on ESP-Now and 2.4 GHz Wifi simoultaneously. One restriction apply, this only works on WiFi channel 1
• and you must therefore set the router to "fixed" channel 1.
• In order to perform the demonstration you will need:
• • 1x ESP8266 or ESP32 programmed with this sketch, acting as Gateway (to the WiFi/internet), and
• • 1-20x ESP8266 or ESP32 programmed with the espnow_sensor sketch and equipped with a temperature sensor
• (or anything else you connect and modify the code for).
• This is a simple demo sketch but fully working. It demostrates simultaneous WiFi and ESP-Now on ESP8266 and ESP32.
• You can add other Internet services like MQTT, Blynk, ThingSpeak etc. (I have been running this for 1.5+ years with
• those services.)

 *    {0x0A, any, ...}

 *  Further, it would be possible to use the built-in HW-MAC address of the ESP8266. But, in case you would need to  
 *  change the ESP (for any reasons) you would then need to update ALL sensors to the same new MAC address. 
 *  It is therefore better to use a soft MAC defined by code. This will be installed in any new ESP HW you may use.
 *  Just remeber to set a new MAC address for every new system (gateway+sensors) you install in paralell. *

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. ... I found some fix this issue, but I dont' know how to use this fix to edit with sketch. please help me,thank you.

I am a newbe to learn about esp-now
