Function recallUnclaimedCrosschainTransfer

recallUnclaimedCrosschainTransfer(connection, pendingTransfer): Web3CustomPromiEvent<void, {
hop: Buffer;
}>
Does almost the same thing as revertCrosschainTransfer but while that function works on transfers that were not delivered to the target chain, this function is used if the assets were successfully delivered to the target chain but not claimed by an account. This will only happen when the target chain has create on transfer account registration strategy enabled and no one claims the target account in time.
Parameters
- connection: Connection
  connection to the source chain. I.e., the chain where the account that originally sent the assets are registered.
- pendingTransfer: TransferRef
  the transfer to recall. Can be acquired using getPendingCrosschainTransfers
Returns Web3CustomPromiEvent<void, {
hop: Buffer;
}>
a promi-event that will emit once for each hop during the recall. It will resolve once the transfer is completely recalled.

Remarks
If this function is called before the transfer has timed out, the promise will be rejected
