How to run Nessus for Skill Assessment

I’m confused in what way I have to connect to the target and run Nessus. I want to use my own VM and conntect to HTB per tunnel.
Do I have to run Nessus in the browser (localhost) of my VM. What is the target-IP? Or do I connect to target as HTB student and run Nessus in terminal. When I do this, it doesn’t find the Nessus-Service.
Funny thing is I ran the scan successfully about a month ago, but couldn’t answer the questions, and now I don’t remember how I did it.

Ok, got it again. I just have to target via the browser via the 8834-port.
