Hello Bjorn Berghmans,
Thank you for reaching out to this Q&A forum.
To get list drive items, you can do Get, sites/site-Id/drives/Drive-Id/items/root/children.
I have 4 items in my drive;
With Get, sites/site-Id/drives/Drive-Id/items/root/children. all of them are showing up.
If you would like to get list of any other sub folder, like channel 2 filder, you can do Get, sites/Id/drives/Drive-id/items/item-id/children.
Hope that helps.
