Add class to list

Is it possible to programmatically add a class to the list that shows all available translations? For example:

<ul class="list-inline">...</ul>

I noticed we can add a class in the MLS options panel in the WordPress admin section, but I was wondering if there´s also a filter that we can use.

Thanks 🙂
