Fusion 360 question - how to delete projects

Ok _ I'm starting to get the hang of this fusion thing a bit - while I'm stuck in it's an ideal time to mug up on my skills.

One thing I'm struggling to do seems increadibly simple but I can't do it .... In getting started I created in my Admin folder in the cloud a whole bunch of unsuccessful and messy attempts - I now want to delete them and tidy up my structure.

Looking on line it says just select delete on th line but you can only do this if you have admin rights. I created these projects and can create more but it won't let me delete - how can I allocate myself admin rights to my own work ? I'd have thought that would have been the default
