I have created a page with RoutablePageMixin and defined a child path. I want to translate this child path based on the active language with gettext_lazy like it works in Django within urlpatterns. I always get 404. Is this even possible or am I missing something?

Here is my Page definition:

class StudyBrowserPage(RoutablePageMixin, TranslatedPage):
    page_description = "Weiterleitung zum Studienbrowser"

    @path('')
    def list_studies(self, request):
        studies = Study.objects.all()
        return self.render(request, context_overrides={
            'studies': studies
        })

    # here I actually want another parameter, but i tried to keep it simple. So don't mind the uselessness of the function.
    @path(_('studie') + '/') 
    def study_detail_view(self, request):
        return self.render(request, template='wagtail_home/study_detail.html')

I have translated the string in my django.po:

msgid "studie"
msgstr "study"

Calling .../studie/ works. .../study/ does not.

Edit:
I think I have all the necessary settings in my config:

“context_processors”:
‘django.template.context_processors.i18n’,

USE_I18N = True
WAGTAIL_I18N_ENABLED = True

I also have wagtail-localize installed.
