M2MDevice API documentation is missing

I was reading documents of ARM mbed client guide, (https://docs.mbed.com/docs/mbed-client-guide/en/latest/Howto/#device-object)
However the ducument of M2MDevice API documentation is missing.
https://docs.mbed.com/docs/mbed-client-guide/en/latest/api/classM2MDevice.html

Hi, thanks. It seems that some content is here but I’ve pinged the docs team to fix this.
