If I do end up having to leave the app running in the background to get unattended access to my phone that is fine. I took the trial and error approach to figure it out so if I am wrong please don't hold it against me. No clue if I did this correctly or if I went through 50 steps when I could have gotten same result doing 5 steps.

I will try the same process with the app closed and see what happens but in the interim this process worked for me. Unsure if this matters but I DID have the TeamViewer app running in the background on my Android phone. I was able to perform all functions without issue. I clicked the "connect" button beside my note 8's device name and it brought up the TeamViewer desktop app and began a connection with my android device without any prompts or need for authorization on my phone. This brought up both my Note 8 and my laptop. After all of this I went to the login page in Chrome and logged in to my account, When the team viewer management console came up I clicked on "My Computers" in the menu on the far left. I also made sure that both devices were added as trusted devices in my TeamViewer account. I did go through the process of allowing unattended access on the desktop app. Once you have your account set-up and TeamViewer installed on your computer as well as TeamViewer app installed on your Android you should be able to.

After some trial and error, I believe that what you are asking is definitely possible. I am also new to this and wondered the same thing.
