Did you find any alternative? https://support.smartbear.com/testcomplete/docs/app-testing/web/cef/about.html https://support.smartbear.com/testcomplete/docs/app-testing/web/cef/about.html Supported CEF versions Which CEF versions are supported depends on the approach to exposing CEF applications: Chrome DevTools Protocol - CEF version 88 (including minor versions) is supported. We do not guarantee support for later versions of CEF. Script injection (legacy) - CEF versions 85.0.4183 and earlier are supported (except CEF3 1750). Note: For CEF applications that use WPF controls, only versions 84.0.04147 and earlier are supported.
