cmd+v in osx appkit/swiftui menu bar hybrid app

I have a swiftui app without storyboard that is a menu bar app (UIElement). In it, I have a swiftui view that is displayed using NSWindowController. In that view, I have a swiftui TextField for which pasting with cmd+v does not work, but right-click gives a context menu offering me to paste (which works). What could be wrong? https://github.com/rrva/gitlab-notifier/blob/main/GitlabNotifier/PrefsView.swift
