Programmable HID USB Keypads [closed]

I have been looking for small 3 or 6 key programmable keypads that use the standard USB HID drivers.
I have seen the X-Keys and renovation keypads but they are too big and bulky.

To be specific, I needs the devices to enumerate on the host with USB Class ID 3, SubClass 1, Protocol 1.

I have tried some small keypads on amazon such as vaydeer and the sayobot but they seem to be using a non USB HID protocol that is not compatible with my use case.

Any further device info would very greatly appreciated.
