Because Gopher for Chrome is designed to be for administrative use only, we do not make it available for forced-installation to user accounts, as this would likely cause confusion if pushed out to non-administrative users.
Instead, to install Gopher for Chrome for multiple users on the Google Workspace domain, each user should follow these installation steps, the same steps as for the first installer of the app.
Once a domain license has been purchased, any user with the proper level of administrative / API access can use Gopher for Chrome in its full, licensed glory.
