In Galaxy 2 how does one set the custom launch options?

I found a support article for Galaxy 1 (https://support.gog.com/hc/en-us/articles/360022948474-Borderless-Windowed-Mode-) but I can't figure out how to do in 2. I have been unable to find a doc/post on this either. Anyone know how this is supposed to be done in 2?

Bump, because I want to know too.

PS: The forum search feature is broken. Searching for "launch options" returned nothing, even though it's literally in the title and first post. I only found this when searching for "launch" instead.

Apparently It can not be done right now. It seems to be one of the features they are working on for next updates.

Changelog
2.0.12 Beta (December 18, 2019)

Known issues:
[...]
- Certain features from GOG GALAXY 1.2 are still missing (launching games with parameters)

I've been waiting a long time for this as well. There is a workaround for the time being, which is creating a batch file (text file with .bat ending) containing the exe and launch parameters. Then you can add the batch file instead of an exe. Not very elegant though, so I hope they will add the launch parameters soon.

Can i just add it to the "Launch ..." shortcut in the game's folder? Or does Galaxy not use it?
