Deploy extension silently

In considering deployment methods, I came across this article for deploying the extension using Group Policy: Deploy Browser Extension to Managed Devices | Bitwarden Help Center

During initial testing, immediately after updating group policy on a test device, the currently open browsers (Chrome, Edge, and Firefox) all opened a new tab with a big fat “Congratulations! You have successfully installed the Bitwarden browser extension” message. Is there a way to disable this? We’d like the installation of this extension to be silent so that users aren’t interrupted in their daily work or suddenly calling our help desk because of some scary popup that just appeared on their screen suddenly.
