Withdrawal Flow
In Optimism terminology, a withdrawal is a transaction sent from L2 (OP Mainnet, OP Sepolia etc.) to L1 (Ethereum mainnet, Sepolia, etc.).

Withdrawals require the user to submit three transactions:

Withdrawal initiating transaction, which the user submits on L2.
Withdrawal proving transaction, which the user submits on L1 to prove that the withdrawal is legitimate (based on a Merkle-Patricia trie root that commits to the state of the L2ToL1MessagePasser's storage on L2)
Withdrawal finalizing transaction, which the user submits on L1 after the fault challenge period has passed, to actually run the transaction on L1.

i has completed ''Withdrawal proving transaction'',but don't know how to ''Withdrawal finalizing transaction''
(i tried to bridge a ERC20 token from blast to ethereum)
