Some translations present in the source file network.js are not shown for translation
GNOME-shell main
See for example: https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/main/js/ui/status/network.js#L1807
this.menu.setHeader('network-wired-symbolic', _('Wired Connections'));
Correctly marked for translation, does not appear in the file for translation:
https://l10n.gnome.org/POT/gnome-shell.main/gnome-shell.main.es.po
In the same file also occurs for Mobile Connections and other strings in the same file.
These strings are very visible in the UI.
I cannot tell if this specific to network.js or if they are more files with this problem
