use `this[]` to get private property inside the class in javascript

It's acknowledge that we can access a property of an object by two ways :foo.bar and foo['bar'], but when I use the new feature # to declare a private member in class, it won't work properly:

class FooBar{
    constructor(){}
    testCall(name){
        this[name]()
    }
    bar(){console.log(1)}
    #bar(){console.log(2)}
}
let foo = new FooBar();
foo.testCall('bar');   //this line works properly
foo.testCall('#bar');  //Uncaught TypeError: this[name] is not a function

Can someone please tell how can I modify it to make the code work properly
