Hello! I have a problem with esp8266 connectin to arduino mega

The Library
1

cayenne:4:10: fatal error: CayenneMQTTESP8266Shield.h: No such file or directory

4 | #include <CayenneMQTTESP8266Shield.h>

  |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

compilation terminated.

exit status 1

CayenneMQTTESP8266Shield.h: No such file or directory

Install the ESP8266SerialLibrary.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) from the Cayenne extras/libraries folder (e.g. MyDocuments\Arduino\libraries\CayenneMQTT\extras\libraries) to compile this example.

Now I have this:

Arduino: 1.8.13 (Windows 10), Placă"Generic ESP8266 Module, 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Executable segment sizes:

ICACHE : 32768 - flash instruction cache

IROM : 255684 - code in flash (default or ICACHE_FLASH_ATTR)

IRAM : 26733 / 32768 - code in IRAM (IRAM_ATTR, ISRs…)

DATA : 1632 ) - initialized variables (global, static) in RAM/HEAP

RODATA : 1744 ) / 81920 - constants (global, static) in RAM/HEAP

BSS : 26184 ) - zeroed variables (global, static) in RAM/HEAP

Schiţa foloseşte 285793 bytes (29%) din spațiul de stocare a programului. Maximul este de 958448 bytes.

Variabilele globale folosesc 29560 bytes (36%) din memoria dinamică, lăsând 52360 bytes pentru variabilele locale. Maximul este de 81920 bytes.

which serial pins are you using to connect the esp with the mega?
