How to activate: Custom Keyboard layout qwertz (

Hi, I installed → Custom Keyboard layout qwertz | — Community Repository System. If I look in settings> system > text input I see the following picture:

I do not find the mentioned new layout “qwertz” to activate it.
How can I activate/use the new keyboard layout (a reboot of the phone didn’t help)?
Phone: Xperia 10 III,

If you tap on “Deutsch, English” behind keyboards (Tastaturen), a menu with all installed keyboard layouts will be open.


Thanks, I had to scroll down to find it.
