Given a transaction that contains the `apply_transfer` operation and the index it's at, this
function retrieves the transaction RID, the arguments to the `init_transfer` operation and
the details of the `init_transfer` as returned by `get_init_transfer_details`.

Throws `"APPLY TRANSFER NOT FOUND"` if the `op_index` does not point to `apply_transfer`

Throws if the `init_tx_op_index` of the `apply_transfer` operation does not point to
`init_transfer` on its `init_transfer_tx`

Throws if the operation preceding the `init_transfer` is not an auth operation

**Parameters**

* **tx** — the transaction containing the `apply_transfer` operation
* **apply\_op\_index** — the index of the `apply_transfer` operation in `tx`

**See Also**

* [get\_init\_transfer\_details](https://docs.chromia.com/pages/ft4-rell/-f-t4-library/lib.ft4.external.crosschain/get_init_transfer_details/) — for information on what details it returns
* `core.auth.is_auth_op` — for information on auth operations
