Where the draw.io diagrams are being stored?

Hi Ali! 

Great question... While there isn’t a dedicated spot to view all your draw.io diagrams, you can search for them in Confluence. If you use the search function and filter by "Created by" (your username) and "Type" as draw.io Diagrams, you will only see the diagrams you’ve created, making the search more precise. You can also look up attachments, but filtering by "draw.io Diagrams" is much more accurate.

As for editing outside the page, you'll need to do it within Confluence on the page where the diagram lives, as they’re tied to the page itself.

Hope that helps! Let me know if you need anything else :)
