+## Refresh user access tokens

+To refresh a token, use the `CommunicationUser` object to re-issue:
+
+```javascript  
+let userResponse = new CommunicationUser(existingUserId);
+let tokenResponse = await identityClient.issueToken(userResponse, ["voip"]);

 ## Delete a user
 
 Deleting a user revokes all active tokens and prevents you from issuing subsequent tokens for the identities. It also removes all the persisted content associated with the user.

 You need to replace `<USER_ACCESS_TOKEN>` with a valid user access token for your resource. Refer to the [user access token](../../access-tokens.md) documentation if you don't already have a token available. Using the `CallClient`, initialize a `CallAgent` instance with a `CommunicationUserCredential` which will enable us to make and receive calls. Add the following code to **client.js**:
 
 ```javascript
-const callClient = new CallClient();
-const tokenCredential = new AzureCommunicationUserCredential("<USER ACCESS TOKEN>");
-let callAgent;

-callAgent = await callClient.createCallAgent(tokenCredential);
