TeamViewer auto start on boot in Raspberry pi 4 without any manual operations

I'm trying to make my Raspberry pi 4 free from my hand in any situations. If something happens I could work remotely from my pc. To do so I choose teamviewer for it. But device could reboot occasionally and even in that I should be able to connect to it if something needs to be done. If the OS in Raspberry pi is window(i don't know if it's possible...) it would be easy because in window an option in teamviewer that make teamviewer start with the system(which means start on boot) worked fine. But in Raspberry pi linux... Here's the problem. I've turned on the option 'start teamviewer with system' and put this command /usr/bin/nohup /usr/bin/teamviewer & > /home/pi/log2.txt in rc.local file. But noting happens... When I reboot the Raspberry pi, teamviewer does not start on boot so I cannot connect to the device without turning teamviewer manually. Linux version of Raspberry pi is "Raspbian GNU/Linux 10 (buster)". Plus I trying to connect to teamviewer with 'ID and personal pwd' way. TeamViewer on PC I'm trying to connect is logged in but teamviewer on the device won't. Nothing prints out in log2.txt...
