com.spotify.Client VS flathub

There is nothing "unsafe" about flatpak. In fact for every package on flathub you can see exactly what the "unofficial" packagers do in the corresponding github repository. For example here is the repository for Spotify, if you look at the json manifest file you can see they are repackaging the "official" Snap with the necessary libraries and scripts to support it running as a flatpak. Everything there is open source and able to be examined.

If you click on the "Manifest" link for the package on flathub, it will take you to where the code that packages the app resides. There you can review exactly what the packager does in the json manifest. Here's the one for the Spotify client, for example, which shows where it pulls in dependencies and where it downloads the proprietary code from (in this case they base it on the snap) and what commands it executes while packaging the flatpak.

Try installing it via Flatpak

Flatpaks builds are made to be reproducible. Everything is done openly and you can check how the apps like for example Spotify where made.

Why not just use the flatpak?

Judging by the manifest, the Spotify Flatpak is built from the Spotify Snap.

No, flatpak doesn't use distributions package managers. It doesn't need RPM/DEB packages to work. Today if you want to distribute a flatpak application, you build it once, upload it to flathub.org and it will show up in countless distributions like SteamOS 3 and Pop_OS!.

if you wanna install in terminal using flatpak please go to : https://flathub.org/ to make your life easier.

Yes you can install anything available here https://flathub.org/

All flathub.org flatpaks are available in Discover. You can have a look there to see if you can find what you need. Discord, Spotify, Zoom, MS Teams and ONLYOFFICE (if you need good MS Office compatibility) are all there. I think it comes with Firefox pre-installed, but I'm pretty sure the Deck UI's non-steam tab comes with a one-click installer for Chrome, if that's more your speed. There's also a Chromium flatpak in Discover.

The Discover store is the KDE application for installing/updating/removing things - which in the Steam Deck is used to handle Flatpaks from Flathub.

Linux users typically do not install software like this, we use a package manager (a bit like the app stores on phones) to install stuff instead. SteamOS comes with Flatpak, so you can go over to FlatHub and start installing stuff.
