Controls which app/extension types are allowed to be installed and limits runtime access.
This setting white-lists the allowed types of extension/apps that can be installed in Google Chrome and which hosts they can interact with. The value is a list of strings, each of which should be one of the following: "extension", "theme", "user_script", "hosted_app", "legacy_packaged_app", "platform_app". See the Google Chrome extensions documentation for more information on these types.
Note that this policy also affects extensions and apps to be force-installed via ExtensionInstallForcelist.
If this setting is configured, extensions/apps which have a type that is not on the list will not be installed.
If this settings is left not-configured, no restrictions on the acceptable extension/app types are enforced.
Prior to version 75 using multiple comma separated extension IDs is not supported and will be skipped. The rest of the policy will continue to apply.
