To put Warframe in English?

I play on the Nintendo Switch and want to put Warframe (English) in English, that the game is English and the servers are English or The Chat because they are all more active than in the German chat

On the calculator you do that on the launcher so where you click "start". The launcher in the top right corner of the tab would have to be set.

Unfortunately, I do not know if it works on the switch similar.
