 When you create a container in Azure Fluid Relay, the JWT provided by the [ITokenProvider](https://fluidframework.com/docs/apis/azure-client/itokenprovider-interface) for the creation request can only be used once. After creating a container, the client must generate a new JWT that contains the document ID (which is really the container ID) provided by the service at creation time. If an application has an authorization service that manages container access control, it will need to know who created a container with a given ID in order to authorize the generation of a new JWT for access to that container.
