Never used Silverblue, but it seems as you can just run AppImages without any problems. AppImages aren’t “installable” per se, as they kinda work like portable executables in Windows: you just download it from the Internet, make the file executable, and bam, you can run it from anywhere. There are, however, AppImage “installers” that put your AppImages on a dedicated folder and make an app shortcut for it in your desktop environment, such as https://github.com/TheAssassin/AppImageLauncher
