How to send USDT with Multi-signature feature in TronWeb

Question

I saw the official document. But it is only for transferring trx.

usdtContract.methods.transfer(toAddress, amount).send() can not use the multi-signature feature.

I alse tried to use triggerSmartContract, here is code:

        const transferData = await tronWeb.transactionBuilder.triggerSmartContract(
            contractAddress,
            'transfer(address,uint256)',
            {
                feeLimit: 100000000,
                callValue: 0,
                tokenId: 0,
                from: multiSigAddress,
                contractAddress: contractAddress,
                PermissionId: 2,
            },
            [
                { type: 'address', value: toAddress },
                { type: 'uint256', value: amount },
            ],
        );

        var signedTransaction = await tronWeb.trx.multiSign(transferData, privateKey, 2);
        const result = await tronWeb.trx.sendRawTransaction(signedTransaction);

But it has an error: Invalid transaction provided

Is there any code example for me? thanks.
