@zyga-snapd: The desktop-launch scirpt does this:

###########################
# GNOME runtime selection #
###########################

if [ -d $SNAP/gnome-platform ]; then
  RUNTIME=$SNAP/gnome-platform
  if [ ! -d $RUNTIME/usr ]; then
    echo "You need to connect this snap to the gnome platform snap."
