Welcome to the Wefugees Community and thank you for your question.
My colleague Fardeen was once giving some information on traveling as a refugee here, maybe there are also interesting for you. Traveling to your country of origin (in your case Cameroon) can cause problems with the German authorities and you risk your refugee status. But I can not think of a reason why traveling to another African country should be an issue (as long as you are fulfilling the requirements to enter the country and stay only for a visit). Do you agree dear @mbeon-fardeen?
I hope this helps and please don’t hesitate to get back to us with any further questions.
All the best
