Get Generative Deisgn Study Thumbnails/pictures

Hey everybody !

Did anyone already succeed to get the thumbnails from his GD study ?
In AppData there is a folder for that, with a subfolder for each study… but mine are all empty…

Do you know if there is a way to export the thumbnails to these folders ?
@JacobSmall, #thesavior, Any idea?

Thanks !!
