Office 365 (2016) click to run - multilanguage

I found i have to support systems with different languages now and am having trouble getting started. When the script runs on an english machine it works fine. I see that the script already catches french during the Welcome Message, but i need to do the same for two show-installationPromts and one Show-installationProgress dialogues.

Here are the dialogues

Show-InstallationPrompt -Message "This will install Microsoft Office 365 ProPlus 2016 for you. Please note that the installation can take up to 45 minutes.nAll previous Office versions will be uninstalled first.nSave all your work and click OK to continue."
-ButtonRightText “OK” -Icon Information
-Timeout 120 `
-ExitOnTimeout $false

Show-InstallationProgress -StatusMessage ‘Installing Office 365 ProPlus 2016. This may take some time. Please wait…’ -TopMost $True

Show-InstallationPrompt -Message “Office 365 ProPlus 2016 Installation is complete.” -ButtonRightText ‘OK’ -Icon Information -NoWait} }

Can someone provide some direction to get me started?
