The option: "embed draw.io diagram" offers me the possibility to create a diagram from a CSV file. This is one of the tab options.
I've created such "CSV" diagram offline (with the offline draw io tool). I uploaded the CSV file to the attachments of the page I want to embed the diagram in.
How can I refer to that CSV? It requests an URL. But if I go to the attachments (in another tab of my browser) and copy the link, it cannot resolve the URL. Error message: "CSV file not found or cannot be accessed. Please check the specified URL".
Is there something I miss? It feels strange that only external sources (e.g. github) are allowed while CSV file is available as attachment.
