Misleading ZIGBEE advertising for nRF52820

So i have a problem with documents for nrf52820 while it's a great chip with good functionality i selected it mainly because all of product details and specifications told me it works with zigbbee.
And while radio is capable of it no sdk for 820 allows for its usage.
Is this functionality being worked on or what?
If not I think zigbee mention should be removed from the spec
Im currently using Nrf connect sdk.
