ES6 project documentation by jsDoc or whatever other tool

I have a Nodejs project made of several folders. Each folder is intended to be a java-like package of classes.

src
    folderA
        A.js
        ...

    folderB
        B.js
        ...
    ...

Each class A, B, ... is exported as a default export, as in:

/**
* 
* @class
*/
export default class A {
    constructor() {
        ...
    }
    ...
}
    ...

However, when I run jsDoc I get some module.exports.html page containing the documentation of all the classes in a single html page, whereas I whould like, of course, a documentation reflecting the structure of my project.

Reading from here it seems that the only way to go is creating my custom template, which is something I wish not to do. It appears to me unlikely that jsDoc does not support the documentation of an ES6 project, since jsDoc supports ES6 classes.

Is the structure of my project somehow wrong? How is it expected to be structured a project made of ES6 classes? Is there a way to reflect the project structure into the documentation by jsDoc? Is there a different tool which could do it instead of jsDoc?
