Import system-installed games into the Lutris library by scanning /usr/share/applications

Dear All,

Currently I have installed a bunch (50 or more) of “system” games in my computer (debian 8). System means installed from official debian repositories.

I can read in github that somebody request this feature to scan and fetch for system installed games:

There, a Lutris developer said that this feature is already done but it is unused feature.

My question is, how I can run such script to find and add automagically my system installed games?

Lutris version installed 0.4.12
