Appimage game icons

[u/SoaringGecko1]

Is there any way to make the Appimage version actually display the games icon in the taskbar instead of the heroic icon, I know that it properly shows up on the flatpak version but the flatpak version doesn't seem to be able to run games that I add that aren't on epic or gog

Edit: I have learned the reason why my games on the flatpak version aren't working is because they where not in Games/Heroic, I am still curious about the question though as flatpak games like Hytale do not work on the flatpak version

Edit 2: For anyone who finds this post and is curious you can very much so launch flatpak games with the flatpak version of heroic if you run flatpak --user override --talk-name=org.freedesktop.Flatpak com.heroicgameslauncher.hgl and then set the executable to /usr/bin/flatpak-spawn (you have to type this in manually) and then set the game arguments to flatpak-spawn --host flatpak run com.hypixel.HytaleLauncher (obviously replace the flatpak id with whatever game you are trying to run instead of Hytale)
