Can I use Zoom without an internet connect? I want to record my Power Point Presentations

When the internet works in my classroom, I have found it convenient to start a meeting (which only I attend), share my screen, and record the presentation.  I then upload the recording to a university course website, so students who missed the lecture can hear it while seeing the slides.  My only problem is that I am in a class room with unreliable internet, so I often don't have an internet connection, and I can't start a meeting through my normal process (open zoom, click start a meeting).  

Is there anyway to start a meeting without an internet connection?
