How can i use Meta Ad Library API with African countries

Hello,

I would like to inquire about conducting research on ads in African countries like Ivory Coast, Nigeria, Niger, Senegal, South Africa, Cameroon, and others. Upon my observation, it appears that these countries are not currently supported. I'm curious to know if this limitation is due to an outdated version of the platform or if there is a possibility for me to manually add the necessary code for these countries.

Thank you for your assistance.

Best regards,
