Datacontract import from Unity Catalog now only supports HOST & TOKEN:
https://github.com/datacontract/datacontract-cli?tab=readme-ov-file#environment-variables-6

However use of tokens for databricks in discouraged.
Instead, we make use of the Databricks-CLI with PROFILES:
https://databricks-sdk-py.readthedocs.io/en/latest/authentication.html#overriding-databrickscfg

Would be great if the datacontracts-cli will support the use of PROFILES here:
https://github.com/datacontract/datacontract-cli/blob/main/datacontract/imports/unity_importer.py#L107

from databricks.sdk import WorkspaceClient
w = WorkspaceClient(profile='MYPROFILE')
# Now call the Databricks workspace APIs as desired...

This way, we can use various auth types such as the "databricks-cli" and the "azure-cli" as well as use of TOKENS or SERVICE PRINCIPALS (client_id/secret).
