Hello, as a computer science student I have caught the fancy of microcontrollers. I am currently trying to do a project whereby a 32 x 16 LED matrix can be controlled via Wi-Fi using an ESP32. The problem is that no matter how many ways I connect it, no matter what programs I upload, the matrix will not light up. I think the problem definitely lies with plugging this in, as it is Chinese hardware the instructions are quite unclear and I think there is a mistake with the numbering of the relevant pins on the manufacturer's website.

After a few hours of failing, I decided to try hooking this up to an Arduino Uno R4, the second microcontroller I own.
Surprisingly, once connected, the diodes lit up on their own, just like in the pictures (I am also sending the wiring diagram):
