Amazon DCV has two new permissions to enable the execution of the extensions:
+ `extensions-server`: Allows to start the installed extensions on the server machine.
+ `extensions-client`: Allows to start the installed extensions on the client machine.

For more information about the permissions files, Refer to [ Working with permissions files](https://docs.aws.amazon.com/dcv/latest/adminguide/security-authorization-file-create.html) in the [ Amazon DCV Administrator Guide](https://docs.aws.amazon.com/dcv/latest/adminguide).
