In the Code + Test tab, the drop down menu doesn't show the subdirectories

My Azure function project structure is as follows:
```
├──
│   ├── __init__.py
│ ├── function.json
│ ├── sample.dat
│ └──
│ ├── file1.txt
│ └── file2.txt
├── .gitignore
├── .funcignore
├── host.json
└── requirements.txt
```
Problem: The sub-directory is not visible in the Code + Test tab.

Details:
- The function is successfully deployed and runs properly, however when I go to the Code + Test tab to navigate the files, the sub-directory is not visible.
- I even tried using Kudu and navigated to ```.scm.azurewebsites.net/wwwroot/``` but got no results (Empty page).
- Additional info: the code in ```__init.py__``` uses the contents of the sub-directory, so this means the sub directory is deployed successfully, but I just can't see/access it.

Is there any way I can access the sub-directory contents?
