How to use GZip compression with .GLB files?

Hello all,
I’m working on a medical project at scene optimization phase.
I used draco compression for scene environment models like clinic and hospital loopy and mesh optimizer for animated characters as advised from this answer (https://discourse.threejs.org/t/draco-animation/10945/6).

How to add .gz extension and use that kind of extra compression on my .GLB models?

I noticed that a lot of answers talked about GZIP but no one explains how to use it.

Thank You.
