How to add the url and urldate to \footcite output?

Question

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!

Cite this\footcite[Vgl.][S. 32-33]{einstein} and this\footcite{laubpage} please.

\printbibliography

The url field is printed by the doi+eprint+url macro, which is defined in the standard.bbx file. To use it with authortitle style (and similar) it must be imported into the macro title:

\usepackage{xpatch}
\xapptobibmacro{cite:title}{%
    \setunit{\addcomma\space}%
    \iffieldundef{labelyear}{}
    {\printtext[bibhyperref]{\printlabeldateextra}}%
    \usebibmacro{doi+eprint+url}%
}{}{}
