Smart Contract Call only show fees (BNB) Not actual transfer amount (USDT-BEP20)

[solaris-rig]

I create smart contract call as per following:
import { useWriteContract } from "wagmi";

const { writeContractAsync } = useWriteContract();

const data = await writeContractAsync({
address: '0x55d398326f99059fF775485246999027B3197955', // USDT Contract Address
functionName: 'transfer',
abi: abis,
args: [
toAddress,
txAmount ,
],
})

Tested on trustwallet mobile

when clicked confirm, it send correct USDT amount.
Please help figure out how to make the wallet show USDT instead of BNB
