How to scan iBeacon in ionic 3?


I have a project that scans a iBeacon, and i had also learned this plugin

I have also googled so many projects for that but can’t get expected result.

Here i had some code that I write for scan a beacon

listenToBeaconEvents() {"didRangeBeaconsInRegion", data => {
    // update the UI with the beacon list => {
        let json = data.region;
        console.log("-------Beacons-------" + JSON.stringify(json));
        uuid: JSON.stringify(json.uuid),
        identifier: JSON.stringify(json.identifier),
        typename: JSON.stringify(json.typeName)

But my question is if i don’t have an UUID of particular beacon then how i can search the beacon?

Please Help me. Thanks.
