Note: if you get the board showing up and the comport but cant upload you need to hold down the reset button to allow the connecton to start!!!
UPDATE: I was never successful with this component, I started a LED project and purchased a different board and have made some success. ESP32 S. Using the Arduino IDE v2 in linux
But then I learned more on the various manufactures and there chipsets. This board was an 8266 and setup like this.
once I had this updated the board started to work, blink that is.
Here is a great resource for these small boards and their support

Buying crappy components off Amazon to learn some tek.

There are a few steps and different links to get things started.
Main info page : https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/get-started-devkitc.html
make sure to install ESP32 in boards manager
click tools, click board, click boards manager
type in esp32 in search
click install
after install
click tools
click esp32 arduino
select esp32 wrover module

another board i have worked with is the ESP32 S this was an amazon purchase also https://fixit.localad.com/led-fix-up/
the arduino ide setup is https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
This is a great presentation on I2C buss but it also sets up the 3 axis accel
Setting up arduino ide in utumbu you have to identify the USB to serial converter, the one present on these boards are the
SILABS CP2102
First you have to identify and then see the com ports
lsusb at terminal
sudo apt install setserial (identifies serial ports)
run sudo setserial -g /dev/ttyS[0123]
