How can I make GUI apps installed in Distrobox launch from KDE's application launcher?

I installed Teradici PCoIP client on my Deck, and added this in pcoip-client.desktop file:

[Desktop Entry]
Type=Application
Version=1.0

Name=PCoIP Client
Comment=Remote access client
Exec=/home/deck/.local/bin/distrobox enter ubuntu-22-04 -- pcoip-client %u
Icon=pcoip-client
Terminal=false
Categories=Network;RemoteAccess;
MimeType=x-scheme-handler/pcoip;

While it worked on Terminal, I can’t make it launch from the application launcher.
