I am relatively new to Kratos. I have a few questions, maybe you can help me with it: 1. How do I make it so that the UI or Ory Elements is set to German or I can set everything myself. 2. When I wanted to build my own components, I once had to filter the CSRF token from the UI Node itself (ui[x]). Is there a better way here? 3. How can I implement a kind of "stay logged in"?
