How to pass a file to be open using command line?

[MocioF]

I have read some issues about it is not possible to open a file in linux (debian/ubuntu) by a click on a .drawio file.
I am writing a Gentoo Linux ebuild for drawio desktop and I am facing the same issue.

Is there a way to pass a filepath to be opened on application startup?

Right now I am opening drawio-desktop with:
$ export DRAWIO_DISABLE_UPDATE=true
$ cd /path/to/drawio
$ ./node_modules/.bin/electron --version="21.0.3" --name="draw.io" --description="draw.io desktop" . ./src/main/electron.js
(I am not sure if the last path to electron.js is needed).
Any help appreciated.

Maybe I found a solution:
./node_modules/.bin/electron . "$abspath" --version="22.1.2" --name="draw.io" --description="draw.io desktop" ./src/main/electron.js

where $abspath is the absolute path of the files to open
