[Scripting] "Cookies disabled" with Extension and InDesign CC 2021 (16.4)

[KlausFriese]

Hi,

We're extension developers and our extension is running on older InDesign versions without problems. The panel opens an website from an server, the site is made with Vaadin - and with CC 2021 I get an "Cookies disabled" message from our site. 

My CEFCommandLine is:

					<CEFCommandLine>
						<Parameter>--disable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecure,NetworkService</Parameter>
						<Parameter>--disable-site-isolation-trials</Parameter>
						<Parameter>--allow-file-access</Parameter>
						<Parameter>--allow-file-access-from-files</Parameter>
						<Parameter>--enable-nodejs</Parameter>
						<Parameter>--mixed-context</Parameter>
					</CEFCommandLine>

Anybody here with a similar problem? Is there a way to access the settings in the Chromium engine?

Thanks
Klaus
