Bluetooth device class

I have a Dell E5570 with Intel Wireless AC 8260 card. I want to purchase bluetooth products that require my PC to have class 1 bluetooth capabilities (see attached image from wikipedia page https://en.wikipedia.org/wiki/Bluetooth

I have spent more then a week googling and looking through spec sheets etc but I cannot find any information on device class in the released specs from Intel nor can I find the required information anywhere else online. Can someone either tell me how to find out what class the above wireless bluetooth card is or tell me how do I go about finding out such information.

Any information provided will be very gratefully received as I am just about pulling my hair out at this point.

Thanks
