I need some help

First of all, I ‘installed’ Flatpak on my Chrome OS device. Don’t see an app icon or anything, I don’t think I’m supposed to… I’m pretty sure it’s installed. Also, yes, I restarted the system.

However, when I downloaded Discord, it downloaded the file, then did the command lines it told me to… the file I attached is what showed up… any help?

You need to add flathub repo first.

flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Then install with

flatpak install discord

You can see all the install Flatpak apps with

flatpak list

That’s because the package in x86_64 (regular PC) only. It isn’t available for your system.

Is there another pacakge my system can install?

By another package, you mean discord alternative?
