How to get real location ids in cluster

[mrosminin]

In order to filter flows after click or on long hover as in example https://flowmap.blue/15kwLB4baXZ7jpip8q0JjgR6zDoS5Gt3gMLCTUAboQxk?v=46.719075%2C7.817990%2C7.51%2C0%2C0&a=0&as=1&b=1&bo=75&c=0&ca=1&d=1&fe=1&lt=1&lfm=ALL&col=Default&f=45

now onClick I get cluster ids in children '{[XXX]}' and real ids in children array.
