Delete online published document in InDesign

Hello guys

I need some help. I've got some docs published via Indesign and I need to delete them. 

I've tried the dashboard and clicked the trashcan but..... nothing happened. I've tried to find something in the online manuals. The only thing I can find is click the trashcan Yes I did... 

Am I doing something wrong? Can someone help me and or tell me what to do? 

Thanks

Hans
