Hello Ado,
The Impressum of your site is not related to the EasyDiscuss component.
It is related to a module you have to create and display in the footer of your Joomla - Joomshaper template.
Here is a link that might help you achieve what you want to do:
Newsberg - Bottom & Footer Design
and also here:
Newsberg - Layout - Module Positions
Also take a look at
Kärcher.de On every page there are multiple modules displayed in the template footer.
On the left there is the company details and on the right a module with menu links with the one linking to the Impressum
