                }
                if(matches.length === 1) {
                    console.log('Updated:', bookmark.key.manga, '=>', matches[0].id);
                    bookmark.key.manga = matches[0].id;
                }
                if(matches.length > 1) {
                    console.warn('Bookmark not updated (need to be done manually in HakuNeko)! Too many matching mangas found for:', bookmark.title.manga, '=>', matches.map(manga => manga.title).join(' || '));
                }
            } catch (error) {
                console.warn('Failed to get new manga ID for: ', bookmark.key.manga, error);
            }
        }
    }
})();

After running, check the output for warnings/errors
If the update failed, simply restart HakuNeko to avoid breaking your bookmark file
If the update was successful, inject the following script to save your migrated bookmark file

Engine.BookmarkManager.saveProfile('default', undefined);
