If I understand this correctly, the request is to extend to 137-138.
Since the origin trial has already run so long, could you please
supplement the information that long extensions require according to
https://www.chromium.org/blink/launching-features/#origin-trials ?

Summary
Support the attestationFormats field from WebAuthn L3. WebAuthn L3
supports a site expressing an ordered preference for credential
attestation formats in the new attestationFormats field[1]. This
feature enables support for this on Android, where multiple formats
can be supported by passkey providers. [1]

WebView application risks
Does this intent deprecate or change behavior of existing APIs, such
that it has potentially high risk for Android WebView-based applications?
None
Goals for experimentation
Reason this experiment is being extended
The Play Services SDK on Android was recently updated with an
equivalent option for native apps. We would like to request an
extension of this trial for two milestones to give Relying Parties
more time to use this option in alongside in websites and native apps.
Ongoing technical constraints
None
Debuggability
None
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
