Dear Fafa Touray,
Thank you for sharing your question with the Wefugees Community!
Please have a look at this thread, in which Melina explained the conditions for the "Beschäftigungsduldung" already very much in detail.
Unfortunately, one of the requirements is, that you have a job for at least 18 months, that pays taxes and social security contributions, and with a regular working time of 35 hours per week.
In general, it is really not easy to get the "Beschäftigungsduldung". Could the "Ausbildungsduldung" be an alternative for you?
Looking forward to hear from you again.
All the best,
