No se pudo llamar a la función de contrato con su firma

La documentación de Web3.js dice aquí que los métodos de un contrato inteligente están disponibles a través de:

1. El nombre: myContract.methods.myMethod
2. El nombre con parámetros: myContract.methods['myMethod(uint256)']
3. La firma: myContract.methods['0x58cf5f10']

pero cuando llamo al método con la segunda y la tercera opción, no pude recuperar el valor, sino que muestra muchas firmas de objetos ... aquí está mi código

async function d () {

  var  myContAddr = '0x8175036782E9564C084eD1DA6C44C27150F24316';
  var myContractAbiDefenition = myAbi;
  var myContractInstance = new web3.eth.Contract(myContractAbiDefenition, myContAddr);

  tokens = await myContractInstance.methods['0xc4e41b22'].call();
  //tokens = await myContractInstance.methods['getTotalSupply()'].call(); // its also give same output
  //  tokens = await myContractInstance.methods.getTotalSupply().call(); // this gives me required output "Tokens :  6"  
  console.log("Tokens : ",tokens);
}
d();

aquí está mi salida
