The installed snap packages wont' create launchers on start menu !
I don't know but it seems this maybe happens with flatpak too.
I'm installing snap packages but i can't find them anywhere !!
I must manually copy the launchers from /snap
There are some background posts about snap and flatpak in the forum.
Sparky4 or Spark5?
What is your DE?
What snaps have you installed? What flatpaks have your installed?
Will it/they open via Alt-F2?
O.K. to post system information as "code" via inxi.
peace out
