How to edit WhatsApp contact in Hub?

I try to edit some contacts of WhatsApp. It's seem only >HUB /contact of phone. However it is not possible on my key2. Could someone help me with this?

Thanks

WhatsApp contacts cannot be edited; they are automatically created as you create standard contacts on your device or sync your contact cards from any cloud profile.

If you want a WhatsApp contact to be edited go to said contact on your device, make your change, save the record and allow WhatsApp to sync; the change should show when the sync is completed. It is not immediate.

Thank you for reply.
