Dear Tafi,
thank you for sharing this question with the wefugee community.
You'll have to apply for a Beschäftigungsduldung at Ausländeramt. You can find the requirements in §60d in Aufenthaltsgesetz: https://dejure.org/gesetze/AufenthG//60d.html
Flüchtlingsrat Thüringen has an application form on its website:
