Support to share app window during screen sharing

This feature is in technical preview from 2408 release.

Previously, the optimized Microsoft Teams call didn’t support sharing an app window running on the virtual session.

Starting from the 2408 version, optimized Microsoft Teams supports screen sharing of specific apps running in the virtual session rather than the entire desktop, which reduces the exposure of information.

For more information about how to share a specific app, feature limitations and more, see App sharing in the Citrix Virtual Apps and Desktops documentation.

Notes:

• This feature is disabled by default.
• To enable the feature, follow the configuration steps.
• To provide feedback about this feature, click the Google form.
• The minimum VDA version must be at least 2109.

Secure HDX

This feature is in technical preview from 2408 release.

Secure HDX is an Application Level Encryption (ALE) solution that prevents any network elements in the traffic path from being able to inspect the HDX traffic. It does this function by providing true End-to-End Encryption (E2EE) at the application level between the Citrix Workspace app (client) and the VDA (session host) using AES-256-GCM encryption.

Prerequisites

The minimum VDA version must be 2402 for this feature to function.

Notes:

• Secure HDX is in technical preview.
• This feature isn’t recommended for use in production environments.
• To request access for this feature, fill out this form.

Configurations

Secure HDX is disabled by default. You can configure this feature using the Secure HDX setting in the Citrix policy:

• Secure HDX: Defines whether to enable the feature for all sessions, only for direct connections, or disable it.

For more information, see Secure HDX in the Citrix DaaS documentation.

Accessibility and TalkBack

This feature is in technical preview from 2307 release.

Citrix Workspace app provides an enhanced user experience with the TalkBack feature. The TalkBack feature helps end users who have difficulty seeing the screen. The narrator reads the screen elements aloud when using the UI.

To use the ChromeOS narrator (ChromeVox), end users must use the keyboard shortcut Ctrl+Alt+Z to turn on the narrator. Use the same key combination to turn off the narrator.

Note:

• By default, this feature is disabled.

How to configure

You can configure the Accessibility feature in one of the following ways:

• Configuration.js
• Google Admin Policy

Configuration.js

To enable the accessibility feature using the configuration.js file, do the following:

1. Locate the configuration.js file in the ChromeApp root folder.

   Notes:

   • Citrix recommends that you back up the configuration.js file before making changes.
   • Citrix recommends editing the configuration.js file only if the Citrix Workspace app for ChromeOS is repackaged for users.
   • Administrator-level credentials are required to edit the configuration.js file.

2. Edit the configuration.js file and add the accessibility attribute. Set the enable attribute to true.

   The following is an example of JSON data:

   'features' :
   {
       'accessibility': {
             'enable': true
           },
   }
