How do Africans especially Ghanaians get the best out this tool and how do we get an affordable subscription across Africa ( West Africa)

I cannot answer on the specifics for Ghanians.

But regarding the subscription:

The self-hosted community edition is extremely powerful and feature-packed. If affordability is the main key, learn how to setup the self-hosted version on server hosted in your region. This will ensure low latency and almost no cost at all.
