Here's the example that does almost everything that I need it to do. The only thing that is missing is that I need the url and urldate to show when using \footcite for online sources. I'd like to achieve something like this:
Laubheimer, Virtual Tours: High Interaction Cost, Moderate Usefulness, 30. Aug. 2020. url: https://www.nngroup.com/articles/virtual-tours/ (besucht am 18.01.2021).
I would greatly appreciate any pointers, thanks!
