HID communication with classic USB library on STM32U5

Hi everyone, I am trying to implement HID communication using the classic USB library on the NUCLEO-U5A5ZJ-Q. Until now I tried to follow this tutorial 

https://community.st.com/t5/stm32-mcus/how-to-use-stmicroelectronics-classic-usb-device-middleware-with/ta-p/599274

Sadly, between the H7 and U5 there are a couple of difference and I can't seem to find a way to make use of this tutorial for it.

I tried to implement the HID Device from this git 

https://github.com/STMicroelectronics/stm32u5-classic-coremw-apps/tree/main/Projects/NUCLEO-U575ZI-Q/Applications/USB_Device/HID_Standalone

but I am not able to merge these file within an STM32CubeIDE project and make it work (I didn't even manage to build it).

Before getting into the USBX version of the HID communication I still want to try to implement one without the use of a FreeRTOS, can somebody help me? Maybe if you already followed one of the links you can tell me what extra steps you did to make it work. Thank you in advance!
