If they're going to play as the great Queen Cleopatra, at least get her ethnicity correct, she was Queek Macedonian and all official data points to her being Greek, though no real text states her skin color her family was considered primarily European. Her family hadn't had any recorded African blood in it; she might have had a bit of Egyptian at the most. However, that was also incredibly rare since Egyptian mistresses were a rarity.
She certainly wasn't black, and most historians agree that her Mother was likely Cleopatra V, not a black woman.
Rewriting history to suit your narrative is the worst thing you can do; you are just misleading the facts and creating more racial discord.
If you want a strong Black African Queen for you to represent, let it be someone who actually is Black African, not already recognised white or olive-skinned Queen.
Though finding a Black African Queen to suit their needs may be hard since they weren't exactly the best of people, especially when it came to slavery. Though that is because making a perfect narrative or representation is always misleading.
