Variable: ALLOW\_UNAUTHENTICATED\_ENV

const ALLOW_UNAUTHENTICATED_ENV: "TEAMS_ALLOW_UNAUTHENTICATED" = "TEAMS_ALLOW_UNAUTHENTICATED"

Environment name for the unauthenticated-messaging escape hatch. Named TEAMS_ALLOW_UNAUTHENTICATED (rather than something softer like TEAMS_DEV) so what it disables is unmistakable in a shell history or deploy manifest.
