Hi,
I just found out that while Moodle's content bank shows all the H5P module's names in English only, the LUMI app can show them translated into other languages.
Please have a look at the new Moodle documentation at https://docs.moodle.org/310/en/H5P#Important_information_for_H5P_users_in_languages_other_than_English and add/remove/change as you see fit.
