Sending Data with ESP8266 to MIT App Inventor

I am trying to use MIT App inventor to display data from Arduino via ESP 8266. I am finding it difficult to find an interface to show the data. What should I use to display real-time changing data?

Here an example with ESP8266

See also the codes for the ESP32

Can a similar example be found in English language?

What example?

I am working on making a real- time parking lot scenario with clock usage. If any example related to this is found in English, it would be very useful

Here more examples of ESP32

The codes for ESP32 are similar to ESP8266. ESP32 has better features than ESP8266.

MQTT and IoT are great friends.

Thanks a lot for this
