How to add a widget to show requesters assigned assets

In SDP how can I show the assets that are assigned to individuals in the self-service portal? 

Ideally, I would like to expand on this.
I would like to show all the requesters assets in one widget and if they are a department head or contain some other permission then they can see all asset that is assigned to there Department or site etc
