SDKInitOptions.licensePopup
The "License required" popup in your own words: its
title (default "License required"), its text (the body, in place of the SDK's sentence naming the reason) and its closeLabel (default "Close"). Each part replaces the SDK's own, and what you leave out stays; a part that is not a string rejects init with INVALID_ARGUMENT. The link is not yours to change: it goes to kernstra.com, where a license is bought. See Licensing.LicensePopupOptions
Example
licensePopupTypeScript
await Kernstra.init({ license, licensePopup: { title: 'Editing is unavailable', text: 'The editor is temporarily unavailable. Please try again later.', }, });
