Through a CheerpJ browser extension
There is one for Forms launched as an applet and one for Forms launched through Java Web Start, so your Forms server and its configuration stay as they are. The extensions run in Chrome, Edge and other Chromium browsers.
Your desktop administrators deploy them through Group Policy or Intune and set the licence by policy, where it activates offline. A self-hosted version serves networks that can’t reach the Chrome Web Store or Edge Add-ons, including air-gapped ones.
