What I’ve already posted should be plenty to go on- it contains all the relevant information. You can see that in my configuration, the extendospartition happens during the ‘specialize’ pass, but from what I understand it can be run in some of the other passes too if for some reason that suited you better.
The technet link I posted mentions the component that contains the setting in Windows System Image Manager, which allows you to add the extendosparition to your unattend.xml
