NWBrowser find all mDNS Services ?

Hello,

i want to find all open mDNS services with the new NWBrowser. With the NetServiceBrowser i got all Services by searching for this type: "_services._dns-sd._udp." but with the NWBrowser i dont get anything. if i search for a specific type like http or companion link i find some devices. How can i get all services with the NWBrowser ? Or is this not possible due to new data collection guidelines ? I tried it in a Playground

import Network

let parameter = NWParameters()
parameter.includePeerToPeer = true
let browser = NWBrowser(for: .bonjour(type: "_services._dns-sd._udp.", domain: nil), using: parameter)
browser.stateUpdateHandler = { state in
    switch state {
    case .ready:
        print("ready")
    case .failed(let error):
        print("error:", error.localizedDescription)
    default:
        break
    }
}
browser.browseResultsChangedHandler = { result, changed in
    result.forEach { device in
        print(device.endpoint)
        print(device.metadata)
    }
}
browser.start(queue: .main)
