Welcome back to the Wefugees Community and thank you for reaching out to us.
We discussed the topic of applying for German citizenship as a refugee already a couple of times on this platform. You may want to check, for instance, this thread or also this website (related more specifically to the process in Berlin though) for more details.
In any case, please also don't hesitate to get back to us if there is any clarification needed or you have any further questions.
All the best,
