Flatpak application service file cannot be fouind

Describe your issue

What's the expected behaviour?

When I start via shell an application that was installed via flatpak, the application should start.

What's the current behaviour?

Some applications installed via flatpak cannot be started from the shell. Starting via flatpak run works.

Running busctl monitor --user reveals the following call which encounters an error:
