Welcome back to the Wefugees Community and thank you for reaching out to us again.
After successfully finished the apprenticeship ("Ausbildung"), you can apply for a residence permit according to section19d of the German Residence Act.
Please see further information in this thread in which my dear colleague Christine explained more on how to apply for the respective residence permit. Here she also mentions that you may apply for a residence permit according to 25b after holding the 19d for 30 months.
Those information are still valid @mbeon-Christine, right?
I hope this helps and please also don't hesitate to get back to us with any further questions.
All the best,
