Bazzite comes packaged with the essentials so that anyone can use it without using terminal. Flatpak is enabled by default and this is the best approach.
You can check it out below.

If you’re not comfortable yet using any other terminal package manager other than apt, you can still use bazzite and learn with time. You can install most apps through Discover (KDE) or Gnome software
I just installed tailscape and it works for my needs. Will read up on your docs. Thx
