Query image / thumbnail picture field from a modern list

Hey, I want to query an image from a modern list item, but as it seems it´s not being indexed like a publishing image. 

I´ve successfully tried to query and display it with a custom webpart via Graph API which is no problem at all, but I can´t make it work the classical way because there is no crawled property with this 'new' image field type. 

This article from Microsoft is not helping at all.
