Summary

This feature introduces an CredentialMediationRequirement enum argument to the CredentialRequestOptions of CredentialsContainer.get() that is intended to replace the currently existing boolean flag CredentialRequestOptions.unmediated. The enum will have three states ("silent", "optional", "required") with "silent" and "optional" directly mapping to the existing boolean states, "required" is a novel option.
