How to display related products

-- url of the page with the problem -- : www.brogaardensisheste.dk/dk/butik
-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.9.13
-- PHP version -- : 7.2.24

I have a big problem having related products displayed. I have checked the documentation and I have done a lot of Google search, but to no help.
I have found this, but I am not able to find the last part of bullit 2:

How to display your related products below your products:
1. Create a new module of the type "HikaShop content module" via the joomla modules manager and leave it unpublished in the joomla options of the module.
2. In the HikaShop options of the module (there is a link to them on the right of the module's joomla options screen), make sure that the "Type of content" option is set to "product" and that the option "Content on product page" is set to "Related products".
3. In the configuration of HikaShop, click on the "Select" button of the "Modules under the product page" option. Set your related module to published and click on OK. Then, save the configuration.

Has something changed since this guide was written?
