Does opemetadata supports adding domain to inltes and outlets?

[C-h-e-r-r-y]

There some examples like that:

    BashOperator(
        task_id="print_date",
        bash_command="date",
        inlets=[
            {"entity": "container", "fqn": "s3_storage_sample.departments", "key": "test"},
        ],
    )

But how to add domain with this? What exact value can I use instead of key?

Thanks in advance!
