## Example

```ts
import { removeApprovedProvider, getApprovedProviders } from '@filoz/synapse-core/warm-storage'
import { createWalletClient, createPublicClient, http } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { calibration } from '@filoz/synapse-core/chains'

const account = privateKeyToAccount('0x...')
const walletClient = createWalletClient({
  account,
  chain: calibration,
  transport: http(),
})
const publicClient = createPublicClient({
  chain: calibration,
  transport: http(),
})

// First, get the list to find the index
const providers = await getApprovedProviders(publicClient, {
  client: account.address,
})
const providerId = 1n
const index = providers.findIndex((id) => id === providerId)

const txHash = await removeApprovedProvider(walletClient, {
  providerId,
  index: BigInt(index),
})

console.log(txHash)
