macOS: how to open nextCloud client window

After installation and configuration I cannot find a way to open the configuration window of the macOS (10.15.4) nextCloud client app ( There is no nextCloud icon in the doc and also my menu bar is very full, so in case there is a nextcloud icon up there, it is overshadowed by the menu items of any application.

I also tried to just run the nextcloud app again, but oddly that does not bring up its window.
