Dear
@Fabido,
thank you for sharing your situation with us.
As for your question- the best option will be a Folgeantrag- the so called second asylum claim. As the facts of your case have chnaged since you can proof the circumstance due the documents you have now. However, I highly suggest you in this case to get the assistnace of a lawyer whose focus is Ausländerrecht.
I hope we could assist you in this, if you have further questions please do not hesitate to reach out to the community.
Best regards,
Nilab
