Bibtex import of custom meta data

[fbernardpi]

Is there a way to directly import custom meta data from bibtex records? It seems that just defining custom meta data fields with the same name as the "pseudo bibtex" tag does not work. Could you point out which part of the code needs to be modified?

For example, I'd like to read to url from the image from a bibtex record like this:
@Article{mykey,
title={My Title},
author={Author A, Author B},
year={2021},
journal={Some Journal},
image = {images/myThumbnail.png}
}
