Can't find Notation Software

I am a musician trying to download the notation software so I can start making music. I have had MuseScore on another computer and had no issues with the downloading of it before. My computer broke down, so I had to redownload it onto my new computer, which is a Chromebook Asus Model C301S. However, every time I try to download the notation software from MuseScore.org (which is supposedly where I can find the notation software), the file takes me to the Sheet Music home where you need to a subscription for downloading sheet music. I wasn't sure if the MuseScore notation software was still free or not, so I thought if I bought a subscription it would make finding it easier because it said one of the features was offline access, which I perceived as the notation software.

So what I'm asking is a couple of questions: Is the notation software free or do you need a subscription to use it, is MuseScore-3.6.2.548021370-x86_64 the notation software that I'm looking for, and if so, how can I navigate it to find the notation software, if not, is there a specific link somebody can show me that will give me just the notation software?

I am at my wit's end and don't have the time or patience to try and navigate this anymore by myself.
