How to create a composite USB HID device on STM32?

Question

Arduino

On stm32, you need to implement a USB HID keyboard and also simultaneously receive data from a PC. With the keyboard, I figured out a little, in which direction to dig in order to do the same receiving data from the host ... can it be possible to make another descriptor at the keyboard and receive data through it?
