please plugin on product page

Hi

We use this plugin on our website https://www.soldoona.com and have a question about its placement on a page.

We would like to show it also on product pages such as this one https://www.soldoona.com/kunst-verkaufen/eule-von-marlies-steinmann/
after the table “Beschreibung” and before the box “?hnliche Produkte”.

How can we do this?

We would like to show not logged in users the links to register and login, once logged in, we do not like to show any content at that place.

Thank you for your support

Regards
Philipp
