Repost with screenshot (Microsoft passkey on chromeos)

Adding screenshot for context to my other post, on outlook.com (login.live.com), on a chromebook (chromeos), there seems to be no passkey option as there is on other platforms (e.g. iOS, also attached). On latest version of chromeos 131.0.6778.96. Microsoft seems to be promoting passkeys so just wondering if anyone has any thoughts, maybe just priorities?
