get Record Id with lightning:Tree

Hi All,  I have a requirement to show object's records in nested-accordian view.. It goes Like Customer(Parent) > Customer Product(Child for Customer) > Suites (Child for Customer Product)

Initially I used Accordian, but I was not able to go third-level.. So, I used lightning:tree for this purpose.. But, with this, I cannot get Id of the record.. Can anyone help with this? 

CMP: 
<aura:component controller="TreeController">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
    <aura:attribute name="items" type="Object"/>
    <lightning:tree items="{! v.items }" onselect="{!c.handleSelect}"/>
</aura:component>

JS
({
    doInit: function (cmp, event, helper) {
        var action = cmp.get("c.getTreeData");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                cmp.set('v.items', JSON.parse(response.getReturnValue()));
            }
            
        });
        $A.enqueueAction(action);
    },
    
    handleSelect: function (cmp, event, helper) {  
        
        var getId = event.getParam('name');
        console.log('>>> getName' + getId);
	},
    
 })

Hii Vigneshwaran Loganathan
Try The Below Code Changes By Me Are In Bold
<aura:component controller="TreeController">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

    <aura:attribute name="items2" type="String" />

    <aura:attribute name="items" type="Object"/>
    <lightning:tree items="{! v.items }" onselect="{!c.handleSelect}"/>

    <b><H6>Selected ID : {!v.items2}</H6></b>

</aura:component>


JS
({
    doInit: function (cmp, event, helper) {
        var action = cmp.get("c.getTreeData");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                cmp.set('v.items', JSON.parse(response.getReturnValue()));
            }
            
        });
        $A.enqueueAction(action);
    },
    
    handleSelect: function (cmp, event, helper) {  
        
        var getId = event.getParam('name');

         cmp.set('v.items2', getId );
    },
    
 })
Please Let Me Know And Mark It As Best Answer If It Helps
Thank You!

CharuDutt - Thanks for the input. but this simply takes "Name" of the record from item and set it in item2. But, I want to fetch Id of the record.

Great - I got my mistake from your screenshot. 

FYI - Below is the snippet from code. 

            cWraper.name = c.Id ; // earlier I had as "c.Name"
            cWraper.label =c.Name ;
            cWraper.expanded =false ;

Thanks for your help!
