I am doing a project to retrieve data from AWS DynamoDB using ESP-32. I now need to send the data from ESP-32 to Arduino Uno via serial communication or any other possible means

Any way to send message from ESP32 to Arduino UNO?

I recommend the Serial Input Basics tutorial. As suggested above, a logic level shifter is required to connect 3.3V and 5V devices. This one or similar will work well.
