How can a USB HID-keyboard and a HID-mouse be combined together to form two USB endpoints in ncs sdk?

[summer]

hi,

    i use NCS SDK V2.80,and dk board is nrf54h20.

     I now want to combine theUSB  HID-KEYBOARD and HID MOUSE into  USB composite device.

    For example, if I want to add hid-mouse to the hid-keyborad project, how do I configure the project and add code? Is there any reference code and instructions? Because the project needed hid keyborad and hid mouse together.
