MicroPython how to achieve communication between ESP32 + RC522 (read and write cards)

I have a module of ESP32 with Micropython firmware, I want to try to connect with mrfc522 to read/write cards, I have read some related articles on the web,
https://www.instructables.com/How-to-Di ... gh-LCD-Wi/
but not using Micropython, I hope someone can give an idea.

RC522 is an SPI module, so you can easily interface it with SPI pins of
ESP32. You need to download its third-party library and you will find ready to run examples to test it out. Try those examples and share your results.

Can I ask you for a link to a third-party library? I'm not quite sure if I can download the right one for that library.

See
this thread which seems quite a compact driver.
I also looked at
this Arduino library which is pretty hairy: nearly 2K lines of C. Clearly there is a lot more to RFID than meets the eye.

Thank you so much! You are really a very kind person. It really helped me a lot! Once I'm done with this project it will be displayed in the appropriate place!
