Help Connecting PN5180 RFID

Hey, I'm new to the ESP32 and electronics in general and am struggling to connect a PN5180 RFID module I bought to the ESP32. I have tried connecting the 5V pin on the RFID to both an external 5V power supply and the 5V pin on the ESP, neither worked but when I plugged it in to the external power supply it got very hot. The ESP is plugged into my laptop and I am using the ATrappmann library and am running the example but all the serial monitor outputs is the "no card found" message. These are the pins it is directly connected to:

ESP32 <--> PN5180
3.3v <--> 3.3V
GND <--> GND
GPIO 18 <--> SCK
GPIO 19 <--> MISO
GPIO 23 <--> MOSI
GPIO 16 <--> NSS
GPIO 5 <--> BUSY
GPIO 17 <--> RST

Any help would be greatly appreciated and ask any questions if I have missed anything, thankyou in advance.

This is the RFID module I am using.
