How do I get Data Source via Odata

Hey, I'm facing an problem with created Data Sources. I want to find them in the Odata Explorer so I've seen this Blog Post: https://blogs.sap.com/2015/03/10/odata-for-sap-business-bydesign-analytics/ but the Post in Outdated and you cannot find the Data Sources nor Reports in "/sap/byd/odata". So my Question is how do I find the data sources now?
