Interfacing (DSI, CSI, I2C, etc.) • Raspberry Pi 3 B+ - Install TZT 1.54 Inch TFT Display 240x240 SPI Interface ST7789

Hello.
I just bought this little LCD Screen:

TZT 1.54 Inch 1.54" Full Color TFT Display Module HD IPS LCD LED Screen 240x240 SPI Interface ST7789 For Arduino
https://www.tztstore.com/goods/show-5477.html
(I bought from another store but is really the same).

Due to my lack of experience, I innocently bought a screen without looking for ready-made projects to use it in Python.

I don't know much about programming.

I tried to follow what was done on some forums, but most similar projects have 7 pins. My board has 8 pins.

I couldn't find any more recent projects for use on RaspianOS 64bits.

I connected the pins as described:

Display PIN Pi PIN
BL GPIO 22 (pin 15)
SCK GPIO 11 SCLK (pin 23)
SDA GPIO 10 MOSI (pin 19)
A0 (DC) GPIO 24 (pin 18)
RESET GPIO 25 (pin 22)
CS GPIO 8 CE0 (pin 24)
GND Ground (pin 9)
VCC 3.3V (pin 1)

The screen lights up but when I run the examples inside pimoroni/st7789-python/ I can't make it work.
I have made some changes into the pimoroni files, putt the pins right number, but had no sucess.

Anyone had already used this TFT Screen Type ?
How do I find help using this ?
