I think I need it for line 17.

+class Profile;
+
+class DurableStoragePermissionContextFactory
+    : public BrowserContextKeyedServiceFactory {
+ public:
+  static DurableStoragePermissionContext* GetForProfile(Profile* profile);
+  static DurableStoragePermissionContextFactory* GetInstance();
+
+ private:
+  friend struct DefaultSingletonTraits<DurableStoragePermissionContextFactory>;
+
+  DurableStoragePermissionContextFactory();
+  ~DurableStoragePermissionContextFactory() override;
