In relation to this issue (https://pulumi-community.slack.com/archives/C84L4E3N1/p1687532809650669), does anyone know how to use fn::Secret in pulumi YAML?

There's an example snippet in the docs: https://www.pulumi.com/docs/languages-sdks/yaml/yaml-language-reference/#fnsecret Although in the case of that issue it should suffice to set "secret" in the configuration section of the YAML as well, and if that isn't work it's a bug on our side.
