Linux Appimage Opens as Different than Desktop File, but as a /tmp/ Mount (KDE Plasma Nobara, Fedora-based)

What I’m trying to do

Have the task manager Obsidian file, from the following obsidian.desktop file, launch Obsidian and have it stay under the Obsidian logo in my task manager.

[Desktop Entry]
Comment=
Exec=/home/jasper/Applications/Obsidian-1.13.7.appimage
Icon=obsidian
MimeType=x-scheme-handler/obsidian;
Name=Obsidian
NoDisplay=false
Path=
PrefersNonDefaultGPU=false
StartupNotify=true
Terminal=false
TerminalOptions=
Type=Application
X-KDE-SubstituteUID=false
X-KDE-Username=

I know it does work, as it works this way on my laptop with the same OS. I’m not sure what is different between the two.

What it is doing

Launching it separately, it gets a ‘W’ icon while in the applications list and if I pin it it gets a ‘?’ icon and clicking it says the file does not exist.

Things I have tried

I typed mount in my console, and this showed when the appimage was open and only when it was open:

/home/jasper/Applications/Obsidian-1.13.7.appimage on /tmp/.mount_ObsidiBUboev type fuse.Obsidian-1.13.7.appimage (ro,nosuid,nodev,relatime,user_id=1001,group_id=1001

Pinning the W icon did not work, as when I close Obsidian, it cannot reopen due to trying to open the /tmp/ file that doesn’t exist anymore.
