How to add the Ubuntu image's running user to groups?

[Avasam]

During install, the python module keyboard runs dumpkeys to extract all key names.
This fails unless the user running the command is in the input and tty groups.

I cannot simply run sudo usermod -a -G tty,input $USER as the groups aren't updated for the current session.
I cannot run pip as root (sudo pip install ...) because this messes up packages installs in a way that breaks both Pyright and PyInstaller.

Is there any solution?

- run: |
      sudo usermod -aG tty,input $USER
      sudo -s -u ${USER} bash -c 'whoami && groups'

Thanks! I did not know about the user -u, --user flag!
