Setting default language in Hotspot

Can someone tell how you change Hotspot Login/Logout User Interface from English to another (eg LV) language as the DEFAULT language? I did find the cross links from EN page to LV and vice versa. Bit it would be nice if the desired language opened automatically. Which file, which context to change? Or, shall the corresponding files from a specific language directory be copied into the root?

Your html docs are in /file in the hotspot directory. If you notice, there is an additional directory called hotspot/lv also.
The setting is in ‘/ip hotspot profile’. Change html-directory=hotspot/lv , and you are now in Latvia!

Exactly!
Thank you!
