 #### Access token authentication requires role assignment
 
-To use the access token approach, you need to generate access tokens. Since access tokens are associated with azure identities, correct role-based access control (RBAC) must be assigned to the identity. The role assignment is on data plane level, and you must have minimum control plane permissions to perform the role assignment.

 The Identity Access Management (IAM) role assignments from azure portal are on control plane level and don't affect the role assignments on data plane. Data plane role assignments are only available via Azure CLI. The `readAnalytics` action is required to read data from analytical store in Cosmos DB and is not part of any predefined roles. As such we must create a custom role definition. In addition to the `readAnalytics` action, also add the actions required for Data Reader. Create a JSON file with the following content and name it role_definition.json
