2. Connect to Azure using Az Cli
3. Create Identity using az communication user-identity 
4. Issue Identity Token for specific scope (voip, chat)


```sh 
az extension add --name communication
$acsName="< acs-Name >"
$resouceGroup="< Resource Group Name >"

$connection=az communication list-key --name $acsName --resource-group $resouceGroup  --query "primaryConnectionString"

$rawId=az communication user-identity user create --connection-string $connection  --query "rawId"

az communication identity token issue --scope chat voip  --user $rawId --connection-string $connection  --query "token"


Note:

#$rawId=az communication identity user create --connection-string $connection  --query "rawId"

#This command is implicitly deprecated because command group 'communication identity token' is deprecated and will be removed in a future release. Use communication user-identity token' instead.
