Pode configurar o controlo de acesso para aplicações de IA ao nível do projeto. Para conceder acesso às aplicações de IA através da consola, atribua a função de administrador do Discovery Engine a um principal para o projeto que contém o motor de aplicações de IA.
Para conceder acesso a aplicações de IA, siga as instruções em Conceda uma única função na documentação do IAM com as seguintes orientações:
No passo 2, selecione um projeto.
No passo 4, quando selecionar uma função, introduza Motor de descoberta no filtro e, de seguida, clique em Administrador do motor de descoberta.
Se for proprietário do projeto, tem automaticamente a função de administrador do Discovery Engine para esse projeto.
Para conceder acesso a aplicações de IA a outros utilizadores, grupos e contas de serviço, consulte o artigo Controlo de acesso com a IAM.
