Great!

Couple things.
Command shall be

sudo python3 TeamViewer-15-id-changer.py

for the latest macOS.

After the first run, when all goes well, you can just run TeamViewer, you don't need to restart the computer.

If you want to repeat this step, you need to restart computer as on 2nd run you will get the error

Error: can not patch file /Applications/TeamViewer.app/Contents/MacOS/TeamViewer
[Errno 1] Operation not permitted: '/Applications/TeamViewer.app/Contents/MacOS/TeamViewer'

After restart, all will work well.
