Add "retrieved on:" only for internet sources

Niki0911

Hello everyone, I need your help. I use the citation style "American Psychological Association 7th edition", but my professor wants "added on:" to be added to the internet sources. How exactly do I have to program this in the editor? Or does anyone have another solution?
I am grateful for any help :)

Greetings Niklas
