Change main menu multi language

Good morning everyone,
i have set up a new website with the NEWSII template that will be available in three languages (English, German, Spanish).
Now i am stuck at the point on how to change the main menu. English is set up as main/default language.

From the start my menu was in english. I now created a second menu in german and create the module for it.
But now i realized that for the main menu there is no module.

So i went to the template are in the Joomla backend and there i saw that i can add only one menu to the template.

Could anyone tell me how to make the menu available in several languages?
Thanks in advance for your time and support,
Carlos
