I can't delete a draw.io diagram from a Confluence page

[Becks Sankey]

I have followed the instructions in another post for deleting a draw.io diagram from a Confluence page.

However, the 'Delete' option is greyed out and unavailable to select.

Hello, can you please check if you are granted the permission to delete attachments in that space? 

I doublechecked it now: I can delete my draw.io diagram as I have the permission to delete attachements on pages in the space.

Thank you, I will locate the site administrator and ask them if I have the right permissions.
