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() {
    this.events.subscribe("didRangeBeaconsInRegion", data => {
    // update the UI with the beacon list
    this.zone.run(() => {
        let json = data.region;
        console.log("-------Beacons-------" + JSON.stringify(json));
        this.beacons.push({
        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.
