/**
* Withdraws funds from the initiated deposit, which failed when finalizing on L2.
* If the deposit L2 transaction has failed, it sends an L1 transaction calling `claimFailedDeposit` method of the
* L1 bridge, which results in returning L1 tokens back to the depositor.
*
* @param client - Client to use
* @param parameters - {@link ClaimFailedDepositParameters}
* @returns hash - The [Transaction](https://viem.sh/docs/glossary/terms#transaction) hash. {@link ClaimFailedDepositReturnType}
*
* @example
* import { createPublicClient, http } from 'viem'
* import { privateKeyToAccount } from 'viem/accounts'
* import { zksync, mainnet } from 'viem/chains'
* import { claimFailedDeposit, publicActionsL2 } from 'viem/zksync'
*
* const client = createPublicClient({
* chain: mainnet,
* transport: http(),
* })
*
* const clientL2 = createPublicClient({
* chain: zksync,
* transport: http(),
* }).extend(publicActionsL2())
*
* const account = privateKeyToAccount('0x…')
*
* const hash = await claimFailedDeposit(client, {
* client: clientL2,
* account,
* depositHash: <L2_HASH_OF_FAILED_DEPOSIT>,
* })
