Customising TeamViewerQS after installation via Munki (macOS)

We use Munki to install TeamViewerQS on macOS. I'm trying to figure out how to apply customisation (logo, background colour, etc) to the TVQS dialog window once it's been installed on the user's computer, presumably through a post-install script.

I found a script that claims to work for TeamViewer Host, but it doesn't seem to work for TVQS. It uses the xattr command to write the configuration ID to the com.teamviewer.ConfigurationId extended attribute. When I do this for TVQS, the app doesn't present any different appearance when launched than it did before.

Thoughts? Am I doing something wrong here?
