`106215` is the pointer of the big map.
`granadanet` to be replaced with `mainnet`.
`tz1KxFpyYzkcgq5CAok8fNvszrRcD2MUFMXy` is the address of the delegator.


The response yields all big map entries for the specified address `tz1KxFpyYzkcgq5CAok8fNvszrRcD2MUFMXy`.

The key of the `deposit` is a tuple of the type `(blockHeight, address)`, which is `(nat, address)`. The`blockHeight` is for each `deposit` *key* in `data.key.children[1].value`.
