Intercepting method calls

Problem statement

Given this object

const myObj = {
  multiply(x, y) {
    return x * y;
  },
  squared(x) {
    return x ** x;
  }
};

and this method

function handleMethodCall(fnName, fnArgs) {
  console.log(`${fnName} called with `, fnArgs);
}

implement this function

function interceptMethodCalls(obj, fn) {
  // TODO
}

so that

interceptMethodCalls(myObj, handleMethodCall);
myObj.multiply(2, 7);
myObj.squared(2);

logs to the console

// multiply called with  [ 2, 7 ]
// squared called with  [ 2 ] 

Notes

If you need to, you can change more than just the interceptMethodCalls function. I've got two solutions and they slightly differ in how the interceptMethodCalls is invoked. But the parameters should stay the same.
