Description

https://github.com/w3c/webappsec-credential-management/pull/224 added a mediation option to CredentialsContainer.create(), to enable websites to support conditional create, AKA automatic passkey creation.

This should be documented on MDN.

In fact it would be good to rework https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API#discoverable_credentials_and_conditional_mediation, to make it clear that it's really about autofill (and to downplay the stuff about discoverable credentials), and move it into a separate guide page that also covered conditional create.

Direção de pesquisa
The issue requests documenting the `mediation` option for `CredentialsContainer.create()` as part of WebAuthn conditional create. The MDN page at https://developer.mozilla.org/en US/docs/Web/API/Web Authentication API#discoverable credentials and conditional mediation should be reworked to focus on autofill and moved to a separate guide page. A separate guide covering conditional create using the specification (w3c/webappsec credential management#224) and Chrome's developer documentation should be created. No existing pull requests or comments are present, so work can start fresh.
