Note: I'm using org-cite, not org-ref.
As I'm writing, I sometimes add a new citation to my references.bib file. But org-mode can't always find it. Instead, org highlights the new citation as an error, and if I click on it says "Cannot find citation key".
However if I restart Emacs, it can find it.
Is there a function I can call to rebuild or refresh org-mode's understanding of the .bib file without having to restart Emacs?
