Hi,

you can't launch an app installed into container crap the PATH way,
until you add a wrapper script or an alias.

  "Running applications

  Once an application has been installed, it can be launched using the
  run command and its application ID:

  $ flatpak run org.gimp.GIMP" -
  https://docs.flatpak.org/en/latest/using-flatpak.html

Don't use snap, flatpack and Co., if you expect to get a sound Unix
alike computer system, that doesn't breaks with reliable conventions.

Since Claws is quite lightweight, it's no big deal to build a deb
package for the latest Claws release, without running into dependency
issues, unless the Ubuntu flavour or derivative isn't a very aged LTS
release.

If you anyway want to use the latest and greatest software, don't use a
release model distro at all.

The snap, flatpack and Co. approach makes no sense at all, it's utter
nonsense.

Regards,
Ralf
