wallet.sendTransaction support

[thebrahman]

I have been trying to add wallet.sendTransaction functionality to avoid blowfish wallet flags.
this is what I have done:

let builder = transactionBuilder()
      .add(setComputeUnitLimit(umiWalletAdapter, { units: 1_000_000 })) // Increase compute units
      .add(
        mintV2(umiWalletAdapter, {
          candyMachine: candyMachine.publicKey,
          nftMint,
          collectionMint: candyMachine.collectionMint,
          collectionUpdateAuthority: candyMachine.authority,
          tokenStandard: candyMachine.tokenStandard,
          candyGuard: candyGuard?.publicKey,
          mintArgs,
        })
      );

    const {
      context: { slot: minContextSlot },
      value: { blockhash, lastValidBlockHeight }
    } = await connection.getLatestBlockhashAndContext();

    builder = builder.setBlockhash(blockhash);

    const umiTransaction = builder.build(umi);
    const web3Transaction = toWeb3JsTransaction(umiTransaction);


    try {
      // Simulate the transaction
      const simulationResult = await connection.simulateTransaction(web3Transaction, { minContextSlot });

      // Save the simulated transaction to file
      const response = await fetch('/api/saveSimulationResult', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({ simulationResult }),
      });

      if (!response.ok) {
        throw new Error('Failed to save simulation result');
      }


      // If simulation is successful, send the transaction
      const signature = await wallet.sendTransaction(web3Transaction, connection, { minContextSlot });
      await connection.confirmTransaction({ blockhash, lastValidBlockHeight, signature });
      setFormMessage("Minted successfully!");

and this is the simulation output:

I get this error when minting:
