Format fullcite of papers with highlighted own names and reduced author list

Question

I want to print my own publications and show that I am an author by highlighting my own name. As some of the publications have over 100 authors I do not want to print all of them (would be ok with some publications with 5-10 authors, but a whole page of names looks ugly). In general I found a solution but there is currently a space that I would love to get rid off if I skip some names (currently: "First Author , ..., I. Me, et al."; should be: "First Author, ..., I. Me, et al.").

There are some additional things that could be improved but they are not that important for me (1. Is my name currently highlighted also in the normal bibliography and not only in my fullciteNEW command; 2. currently several fields like volume, doi etc. are included in a static fashion; 3. if the number of authors is below 10 it would be fine if all of them are presented.)

Here is current code to represent the status:

        issn = {12345},
