Remove css from plugin

The langswitcher plugin comes with it’s own css (built_in_css: true). How can I remove that css without hacking the plugin’s config directly?

Thank you

Sorry, my bad. Found it. Put a langswitcher.yaml inside user/config/plugins and make changes there.

Via Admin if you change the configuration of a plugin, it will automatically save your own changes to user/config/plugins/*. Manually, you did the right thing.
