Dear @Nevv,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
First of all, it is great news that your application has been approved! I am not too sure if the immigration authority (Ausländerbehörde) will actually inform your employer as well about it. I think it is best that you send a copy to the company to be sure. In any case, please don't hesitate to keep us updated or to get back to us with any further questions.
All the best,
Meike
