Insert listing -- from file?

Thanks,

Minted uses styles which you can set with the style option, in preamble

\AtBeginDocument{\setminted{style=name}}

Hm...

Inserting this command, and setting "style=default" produced the usual thing,

[cid:177de988-84d4-4f1e-b062-3bc26e05412c]

Changing to "style=colorful" produced a slight change, but not as expected,
[cid:7f4be5cf-0083-4a95-a861-a3328f648ebf]

I have used Google AI Studio to produce the preamble... Maybe AI Studio has messed up? Here is my preamble:

% ----------------------------------------
% My personal math package
% ----------------------------------------
\usepackage{C:/Users/Bernt/OneDrive/.../berntmath_mnt}

Two comments to the "berntmath_mnt.sty" file content (below)...

  1.
AI Studio added some code to make the boxes with drop shadow have equal width in the "listings" code and the "minted" code, and the same thickness of the drop shadow.
  2.
AI Studio added some code to "simplify" the insertion of the file name "JuliaUnicodeFile", but has not been able to figure out how to specify caption and label ― so maybe this "simplification" was a mistake.

My "berntmath_mnt.sty" file (I delete the math macros to make it shorter...):

Anyways, if anyone with some experience sees what is wrong, please let me know. (Both the color choice in minted that doesn't work, and the possibility to insert caption + label for minted code ― this works for listings code).

Minted uses styles which you can set with the style option, in preamble

\AtBeginDocument{\setminted{style=name}}

Available styles are here:
https://pygments.org/styles/

If you insert the listing from a file: In the settings dialog of the
file/programlisting insert inset.
