make onTransaction insight not wait for promise

[Arch0125]

In the following code snippet inside onTransaction block

const tx = await aa.createSignedUserOp({
    target: (transaction.to as unknown) as string,
    value: (transaction.value as unknown) as string,
    data: (transaction.data as unknown) as string,
  })

  const client = await HttpClient();
  await client.sendUserOpToBundler(tx);

  return {
    
    content: panel([
      heading("Welcome to AA Snap!"),
      text(
        "If you want to sign using your **SCW**, please click the **REJECT** button below."
      ),
      text(
        "You will be taken to the AA Snap UI where you can sign the transaction."
      ),
      text("or **CONFIRM** here to sign using your **EOA**"),
      heading("Transaction details :"),
    ],),
  }; 

Is there a way snap could return the insight without waiting for the signing since it's not accessing any data from it
