I'm trying to delete the folders in the Ubuntu 19.04 application drawer.
I tried with this command
gsettings set org.gnome.desktop.app-folder children's folder  but it only works temporarily until a reboot is done.
After restarting the folders are again.
I've added this command in the startup applications so that it runs once the system is powered on, but it only works for a few seconds because it seems that ubuntu resets the folders to the startup and my start command is executed before it runs and the effect is brief.
