Language in LoginSignupForm.tsx

I'm building my first wasp based on the saas app template and I want to first translate everything to Spanish. I've changed the language everywhere but in the Language in LoginSignupForm.tsx I cannot as it is imported. So then I click to Log in, some text is in english.

I would like to know if there is a multilanguage feature I didn't discovered yet, or if the test in LoginSignupForm.tsx can be changed.
