If your Client has a gateway set up, you can enable a specific application for users instead of deploying full Cloud Desktop for them. The way it works is that after logging in, only the selected application would open for user directly without accessing the full desktop.

In the portal, select the deployment and open the deployment settings by hitting the gear on the top right of the dashboard. Then move the slider “RD Gateway” to the right. After that do the same to the "Enable Remote app" slider.
If you are enabling RD Gateway now, you will need to upload SSL certificate and password to save your settings.
Once the gateway is set up and Remote app is enabled for the client as described above, you can continue to Applications module. Select the application you want to enable for remote access and make sure it's installed in the server. the app will appear with a blue dot under the status.
Assign users that will have the published app available. Click the pencil icon:

Enable the remote application and Save the settings. After they are applied, assigned users will access the application via the web link. The link will consist of the gateway address /RDWeb.
After authenticating, the user will see his assigned resources as below:
