Remarks
Requests the system to actively scan for routes based on the router's route discovery preference. You must call cancelScanRequest(ScanToken) promptly to preserve system resources like battery. Avoid scanning unless there is clear intention from the user to start routing their media. scanRequest specifies relevant scanning options, like whether the system should scan with the screen off. Screen off scanning requires Manifest.permission.MEDIA_ROUTING_CONTROL or Manifest.permission.MEDIA_CONTENT_CONTROL. Proxy routers use the registered RouteDiscoveryPreference of their target routers.
