The whole Connections integration in Teams is only usable when working with Teams set to default colors.
If using the dark mode, many Connections dialogues, (like choosing a Community, choosing a file, etc.) are barely readable.
Of course, it would be nice, to also have a "real" dark mode for the Connections content, but lets focus here on the dialog modals of the Teams app.
So please, provide support for using that in Teams dark mode.
