[Bug]: Error message on startup [Minor]

[RGD2]

Describe the bug

Error dialog on startup after restarting Bottles after choosing 'add a desktop shortcut' for an item, getting linked to a help page about changing permissions (flatseal was used to an an 'other files' access exemption for xdg-data/applications)

Appears to have used 'USER' in place of '$USER' when building a path?

To Reproduce

Start app.
Not sure about a reproduction sequence.

Package

Flatpak from Flathub

Distribution

Debian trixie
