Newbie: I baught a ESP32 with a weird pin layout. How to identify GPxx pins?

[NiklasG]

Hello everyone,
this is my first time working with an ESP32. But I have some Arduino experience.
I baught an ESP32-WROOM-32D and now I try to find documentation to the pin layout but cant find it (I didnt know there are SO MANY different versions).
My plan is to follow a tutorial to connect a round display (GC9A01) with the ESP32, because my Arduino is so slow and has not enough memory for bigger pictures.

My problem is, that I cant find the following GP Pins, because my ESP only has "Dxx" Pins and i cant find good documentation about it.
How can I identify the following pins?

GP23
GP18
GP22
GP16
GP4

The only pins I can identify are the GND and 3v3 ones

Thank you for helping!!

This site here looks like the same pinout you have.

Also, legit boards from espressif can be found here.

Basically treat the Dxx pins as GPxx.
