Brand filtering

Hello,
we’re using YITH WooCommerce Brands Add-on for our shop, but the brands won’t show up in your filter. We were using WOOF – WooCommerce Products Filter before, where the brands were visible, but we’d like to try your plugin as we’re not really happy with WOOF.
Is there any possibility how to add the brands to the filter, please?
Thank you,
Kamila
