MDCSnackbarFoundation Class usage

How do I use MDCSnackbarFoundation ? with MDCSnackbar

This documentation is not clear enough to get an idea. https://github.com/material-components/material-components-web/tree/master/packages/mdc-snackbar#using-the-foundation-class

This is my code and I need to bind MDCSnackbarFoundation for it.

logger = new MDCSnackbar($selector[0]);

Thanks
