Hi there!
You can set the citation style
I think in your case it would be " apa", which would result in (Einstein, 1905), so
#bibliography("works.bib", style: "apa")
This code also changes the citation style in the bibliography. If you don’t want that, you can also do
#set cite(style: "apa")
in the beginning of your document.
If there are any questions left, don’t hesitate to ask again
