Can't delete published link

I know there are a few posts in the forum about this but I got no solution from them. Yes I test-published a report to the web and now I want to delete it using "Manage embedded code". However the messages says "You don't have any embedded code". This is strange because firstly the publishing process went through and the link is created, and secondly I can apparently view the report in the web link created.

I tried looking around in different workspaces that I can access but just wasn't able to find it. Could you help please?

Thanks
