Slicer version 5.1.0, revision 30927, built 2022-05-09, MacOS

I tried to follow an example for loading dicoms form the [Script repository — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#import-dicom-files-into-the-application-s-dicom-database), however

```auto
slicer.modules.DICOMWidget.browserWidget.dicomBrowser

```

does not work, it throws only the following error:

> AttributeError: module ‘modules’ has no attribute ‘DICOMWidget’

This is how it is supposed to work: module widgets are only instantiated when they are needed (i.e., when you switch to a module the first time). That is why the script example starts with switching to the DICOM module.
