Multi currency

Hi, i understand that once i turn on the multi currency i can't go back. I need then to make sure it's worth it.  I will start receiving payments from different countries in Africa and i need to make sure that their currencies are available in QBO: XOF, GHS and NGN. If they are not on the IHS Markit list it's useless to turn on multi currency on my hand. Where can i find the list to verify?

Thanks
