HazelcastIdempotentRepository using existing Hazelcast service on Fuse/Fabric

Issue

I have a working camel HazelcastIdempotentRepository example as follows:

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/blueprint"
       xsi:schemaLocation="
       http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
       http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">

    <bean id="idempotentRepoHazel"
        class="org.apache.camel.processor.idempotent.hazelcast.HazelcastIdempotentRepository">
        <argument ref="hazelcast" />
        <argument value="repo" />
    </bean>
    <bean id="hazelcast" class="com.hazelcast.core.Hazelcast"
        factory-method="newHazelcastInstance">
        <argument>
            <null />
        </argument>
    </bean>

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="direct:start"/>
            <log message="------------------- Original message received -- body=${body}"/>
            <setHeader headerName="messageId">
                <simple>${body}</simple>
            </setHeader>
            <idempotentConsumer messageIdRepositoryRef="idempotentRepoHazel" skipDuplicate="false">
                <header>messageId</header>
                <filter>
                    <property>CamelDuplicateMessage</property>
                    <to uri="mock:duplicate"/>
                    <stop/>
                </filter>
                <log message="+++++++++++++++++++++++++ Message received through filter -- body=${body}"/>
                <to uri="mock:result"/>
            </idempotentConsumer>
        </route>
    </camelContext>
</blueprint>

Now, as can be seen, this example creates a new Hazelcast instance of its own. This is not optimal.
I am wondering if you have an example as such that the HazelcastIdempotentRepository refers to an existing Hazelcast service instance/repo (ideally unified one that is shared by all containers in a same fabric)?
