Hello, when trying out the editor to see if we can integrate it in our app I noticed the `fullScreenButton` is documented but I am unable to hide it, this button doesn’t work (because nested iframe) and thus I’d like to remove it.

```javascript
WebViewer({
    path: '/js/pdfjsexpress/',
    initialDoc: 'pathtopdf',
    disabledElements: [
        'fullScreenButton',
        'fullscreenButton',
    ],
}, document.getElementById('viewer'))
    .then(instance => {
        const {docViewer} = instance;

        instance.disableElements([
            'fullscreenButton',
            'fullScreenButton',
        ]);
    });

```

I’ve tried the above which covers all cases to disable the button I think.

I also noticed the button (row) is missing the `data-element="fullScreenButton"` which is probably related (the dark mode button is also missing this `data-element` so might also not be disableable).

We have version 7.0.1 currently (downloaded from the website at the time of writing this comment).

Hi!

This is fixed in version 7.1 (just released today).

Thanks,

Perfect, although it is now called a `fullscreenButton` and not (as documented) a `fullScreenButton`, you might want to update that in the documentation (and also add `themeChangeButton`) 🙂

But confirmed fixed in 7.1.
