Google Chrome	70.0.3538.16 (Official Build) dev (64-bit)
Firmware Version Google_Caroline.7820.384.0

# Enable ChromeVox with ctrl + alt + z
# Go to Settings > Languages and Input > Add languages and add another language
# Go to that language's menu and check "Display Chrome OS in this language"
# "Restart" button appears
Expected: screen reader is prompted to the existence of the restart button
Actual: no mention of it appearing

There was discussion in the past that this may be by design. However, I argue that screen reader users should get notified and access to everything a visual user would get.

Also very similar to bug 870765
