WebAppInstallByUserEnabled

This policy controls whether users can install web apps through the browser. If you enable or don’t configure this policy, users can install web apps through the browser. If you disable this policy, users can’t install web apps through the browser and the "apps" data type will be excluded from synchronization for Chrome Sync. This policy doesn't support dynamic refresh. Any changes, whether enabling, disabling or unsetting, become effective only after the browser is restarted. This policy doesn't affect the 'WebAppInstallForceList' policy.
