In 18.04 I could set the size of thumbnails in Nautilus by adjusting the dconf setting org.gnome.nautilus.icon-view thumbnail-size
as mentioned in
https://askubuntu.com/a/1097952/680632
and

I recently upgraded to 19.10 and the thumbnail-size
key seems to be gone. Am I missing something or is there a new way to set the thumbnail size?
