ThinOS 2405 - Create web browser shortcut on desktop (URGENT)

Hello, i'm using WMS to deploy config on Dell optiplex 3000 TC.

I created a new group for a few number a thin client, i want to only create a web shortcut on the desktop for them.

I read this note (https://www.dell.com/support/manuals/fr-fr/optiplex-3000-thin-client/thin_os_2402_2405_rn/wyse-management-suite-and-admin-policy-tool-updates?guid=guid-a187b68b-1c7c-4041-9b51-b4bcf163af5a&lang=en-us), it tell that i need to install ThinOS Extension package to be able to create them in the VDI Menu.

But i don't find this package in the download page.

Is this way the only way to do this ?
