How do you set another lang/locale than English on the LMS?

I’ve been running a local container of the Frappe Learning (LMS) and I am curious to know how to make it multilingual, if there is something already existing. Either to configure the settings for the app to be in a single language like french, german or italian, either to have a localization switcher to let the user select their prefered locale. As I am totally new in the project, thank you in advance for your kind reply. Best regards
