How do I include the draw.io diagram when exporting whole page to HTML?

Question

We use the Export to HTML function for some of our Confluence pages. Draw.io diagrams are on these pages. However, when I export a page to HTML from Confluence, diagrams do not appear embedded in the exported HTML file nor in the attachments. Is there a way to include draw.io in the HTML export?

We'll need a detailed example, could you email support@draw.io and include the diagram attachment and storage format for the page please?

What versions of Confluence Server and of draw.io are you using?
