Welcome to our community and thank you for your question!
You can go to any driving school and sign up for the training. They will guide you through the procedure.
You will need documents that prove your age in some way. If you can provide a passport or your Aufenthaltstitel that should be sufficient.
All refugees are allowed to make a driver's license - the legal status is not an obstacle (see the information provided in this thread for example: https://www.wefugees.de/k/questions/1730
). But keep in mind that it will cost quite some money. Depending on how many lessons you need and in which city you take the lessons it can be an amount of up to ~2000€. You can apply for financial aid by jobcenter though, if for example your employer attests that you need a license to do your job.
I hope this answer was helpful to you.
