Hello @Kieu Truong , Azure AI Face service
is one of the services under Cognitive Services/Azure AI services. Please go through this documentation to understand more about the various Azure AI services: https://learn.microsoft.com/en-us/azure/ai-services/what-are-ai-services#available-azure-ai-services
Coming to your second question, as I mentioned earlier, you can create a Face resource in the Azure portal. Once the resource is created you can refresh the studio to see the changes.
Otherwise, you can also create a resource using Vision Studio as mentioned here, firstly sign into the studio with your Azure account, then select settings (gear) icon->choose create a new resource option.
I hope this helps.

Vasavi
