Enable User Web App Install From Browser

This policy controls whether users can install web apps through Microsoft Edge. 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 is excluded from synchronization. This policy doesn't support dynamic refresh. Changes to this policy, whether enabled, disabled, or not configured, take effect only after the browser is restarted. This policy doesn't affect the 'WebAppInstallForceList' policy. Web apps specified by that policy are installed regardless of this policy setting.
