Internal links (SOLVED)

Hello, I’m a student and would like to know if I can change the behavior of html links.

I’m using the Viewer mode but still when I click on links they are opened as a new tab in my default browser.
I’d like to change it so the pages are displayed inside of the exe.

I haven’t had a look at all the tutorials yet but didn’t find anything I was thinking about, is there even a possibility to do this?
My goal is to make a dynamic presentation where you not only can navigate yourself by the toc but also by simply clicking at the links.

Thanks in advance

Edit: Nevermind, I picked the wrong mode for my needs ^^

It can be done only by internet mode and not viewer mode.
I hope this is useful.
