Questions about Logitech MX Keys for Business

Which keyboard is used? I had Qwertz in the search query, but the pictures show qwerty. I would definitely like to have the German version.

Good day Are the umlaut keys Ö / Ä available on this keyboard? In the product pictures they are present on some but not all. If they are not there, can they be programmed by selecting the keyboard layout CH-Switzerland in the PC settings? Kind regards
