The allowlist is a list of origins that takes one of the following values:
*: The feature is allowed by default in top-level browsing contexts and all nested browsing contexts (iframes).
'self': (Default) The feature is allowed by default in top-level browsing contexts and in nested browsing contexts (iframes) in the same domain. The feature is not allowed in cross-origin documents in nested browsing contexts.
'none': The feature is disabled in top-level and nested browsing contexts.

SecureCorp Inc. wants to disable the Geolocation API within all browsing contexts except for its own origin and those whose origin is

FastCorp Inc. wants to disable
geolocation for all cross-origin child frames, except for a specific <iframe>. It can do so by delivering the following HTTP response header to define a feature policy:
Feature-Policy: geolocation 'self'
Then include an allow attribute on the
<iframe src="https://other.com/map" allow="geolocation"></iframe>
iframe attributes can selectively enable features in certain frames, and not in others, even if those frames contain documents from the same origin.
