How to use the @dicebear/avatars function in @dicebear/avatars

// Check whether the image exists at Gravatar.
          await request.head(gravatarUrl).promise();

          res.redirect(gravatarUrl);

          return;
        } catch (e) {
          // No image available at Gravtar, therefore no forwarding.
        }
      }

      res.status(200);
      res.setHeader('Content-Type', 'image/svg+xml');
      res.setHeader('Cache-Control', 'public, max-age=' + ms(privateConfig.apiHttpCaching) / 1000);
      res.end(new Avatars(spriteCollectionPackage(options.cast(requestOptions))).create(seed));
    } catch (e) {
      console.error(e);

      res.status(500).end('Failed to load package ' + spriteCollection.name);
    }
  }
);
