Done. I fwd declared AtomicString.

+namespace blink {
+
+class ScriptState;
+class ScriptPromise;
+
+class Permissions final
+    : public GarbageCollectedFinalized<Permissions>
+    , public ScriptWrappable {
+    DEFINE_WRAPPERTYPEINFO();
+public:
+    virtual ~Permissions();
+
+    virtual void trace(Visitor*);
+
+    static ScriptPromise query(ScriptState*, const AtomicString&);
+};
+
+} // namespace blink
+
+#endif // Permissions_h
