This anonymity feature (where some devices can reconstruct original static address and identify the device while it looks random to all the rest) is available only for bonded devices which exchange necessary anonymity keys. So each such device would need to connect, pair and bond with your advertiser. If you want to go that road see nRF5 SDK \components\ble\peer_manager module and look any example which uses it as hint. If you don't want to do all this and you are fine with just anonymizing the advertising address for all observers then search for "random address" on this forum, there are so many Q&S on this topic...
