Possibility of opening an extension within another extension in Autodesk Forge

Question

Is it possible to open a custom extension thorough another custom extension ?

I tried but I get issues at the time of "Autodesk.Viewing.UI.DockingPanel.call" not sure whether I have done it properly or it is possible at all .

My use case :

I need to create a report, which contains some additional data that needed to enter at runtime plus a screenshot of the current view.( for this i have one extension).

Above extension need to open through markup extension so I can add annotation and save the screenshot. Cheers

edit

is it possible to add a custom extension to a core extension as well ?

viewer.loadExtension("Autodesk.Viewing.MarkupsGui").then(function (extension_)
{
    viewer.loadExtension('CreateNcrExtension');
});

This actually doesn't work . No error but wont load as well

Loading extensions from another extension is common, and usually done in your extension's load method. The load and unload methods can be async, so you can do something like this:

class MyAwesomeExtension extends Autodesk.Viewing.Extension {
    // ...
    async load() {
        await this.viewer.loadExtension('Autodesk.Viewing.MarkupsCore');
        return true;
    }
    // ...
}
