Simple remix, little bit prolonged, so that you can push trough the Wifi cable

Maybe there is a better solution, but just in case you bought this board from Ali - ESP32 Wroom 32 with USB-C - https://www.aliexpress.com/item/32964479255.html - with CH340C chip, you must cut VCC to get antenna working or to improve Wifi without the antenna overal.

Note to the print - the LED holes might be not perfectly aligned but you can always post adjust it in Prusa Slicer.
Also I glued the ESP32 board with hot-glue gun to secure it.
