Linux Desktop Client does not start minimized (version 3.4.2, Pop!_OS 22.04 LTS x86_64, Gnome 42.1)

Nextcloud client for Linux starts up at boot with main dialog window open. In order to close it I need to click the tray icon, choose Open Main Dialog, and then click the tray icon again.

The startup command has the --background tag:

"/usr/bin/nextcloud" --background

In terminial the command:

nextcloud --background

also opens the main dialog window.

Anything I am missing here? Is it possible to start in tray only on Gnome 42?
