Example on assets_ignore format

Hi I was wondering how we should write the format of our assets_ignore to ignore subfolder(s)?

My Folder structure like the following:


and my dash initiation is as follows:

app = dash.Dash(__name__, server=server,
                 assets_folder='../src', assets_ignore='.scss')

So I would like to ignore the js/bin file as well as the sass file.

I could not even ignore the sass file alone. Have tried things like ./sass ./sass/ etc.

The documentation shows we need to pass string to assets_ignore so I am not sure omitting multiple files is feasible at the first place, but even for one file how should we ignore it?

P.S. My current workaround is just ignore all .scss files by writing things like above.
