I'm trying to register an application in Azure following these instructions in the link below.
I go to "App Registrations > New Registration" get the error "Access Denied You don’t have permission to register applications".
My user permission in the Azure Portal is Owner.
I can't find what permissions I need to set for my user so I can add a new app registration.
Owner role is an Azure RBAC role and is not the same as Azure AD directory roles which you need to register apps. Azure RBAC roles apply to subscriptions and resources within them. Azure AD tenants are above subscriptions.
Your Azure AD admin needs to give you at minimum Application Developer directory role.
