Cannot find Dark Mode

[Matres 0]

I used to have dark mode enabled on my Android 7 phone. Now I got a new phone with Android 10 and I cannot enable dark mode / theme.

The guide says it should be under the menu but it is not.

My screen: see attachment

I also can't find it in settings. Where do I enable dark mode?
