How to version QS objects?

Hello, i have been trying to use the describe-dashboard-definition cli command but i get the following error:

Invalid choice: ‘describe-dashboard-definition’, maybe you meant:

describe-dashboard-permissions

Any idea what might be the reason?

Cli command used:
$ aws quicksight describe-dashboard-definition --aws-account-id *********** --dashboard-id ************** > description_output.txt

Thanks,
Nikolas
