Doesn't generate a relation of type 'Composition'

[sorryb]

I have tried to generate the code for a Composition but it always display a Association diagram.

For this:

    namespace Composition
    {
        public class SecondClientInstaller
        {
            DBLogger logger = new DBLogger();
        }
    
        public class DBLogger
        {
        }
    
    }

we get
@startuml
class SecondClientInstaller {
}
class DBLogger {
}
SecondClientInstaller --> "logger" DBLogger
@enduml

The console app has net48 but with net5 was the same.
