How to use the @loopback/metadata.MetadataInspector.getAllMethodMetadata function in @loopback/metadata

export function describeInjectedArguments(
  target: Object,
  method?: string,
): Readonly[] {
  method = method ?? '';

  // Try to read from cache
  const cache =
    MetadataInspector.getAllMethodMetadata[]>(
      METHODS_KEY,
      target,
      {
        ownMetadataOnly: true,

      options.ownMetadataOnly = true;
    }
  } else if (Object.prototype.hasOwnProperty.call(target, method)) {
