Typesetting "et al" in italics with natbib

Question

It looks I'm dealing with an entient problem here but I seem not to find a solution. I'm using Jabref and LaTex(natbib) and I want my reference to appear like this in the text: Peter et al.(2023) i.e, with an italic et al. #Italic "et al".

I've tried everything, this is potentially my last hope.

Even if not supported by default, you can customize the bibliography style file

Modify appropriately the .bst file to ensure

\emph{et al.}

Here is a fully working example on GitHub which you can fork and test under your Overleaf account.
