SAP Cloud CCv2 Datahub setting datahub.encryption.key.path

When setting up CCv2 with datahub you create a folder config under datahub and you place in here datahub-environment.conf datahub-environment-d1.conf * encryption-key.txt

So in datahub-environment-d1.conf is it correct to add datahub.encryption.key.path=encryption-key.txt or should the path be something else?
