I have frequently created articles and had Wikidata linked to the article. Take https://en.wikipedia.org/wiki/Kate_Baker - if you click on Wikidata item, then it takes you to: https://m.wikidata.org/wiki/Q21536118
It seems like magic, but it is possible to entirely outsource the infobox to wikidata. See for example https://fr.wikipedia.org/wiki/Mart%C3%ADn_Abadi whose infobox is created with the sole `{{Infobox Biographie2}}` line.
