Login to your Umbrella console
Under Deployments/Core Identies/Roaming Computers, click on the Roaming Client download button in the upper right.
On the overlay screen, at the bottom is a link to "Download Module Profile" That will give you an "Orginfo.json" file
Place that on your firewall as an umbrella profile, and anyone connecting will get it. You can also just drop it in C:\ProgramData\Cisco\Cisco AnyConnect Secure Mobility Client\Umbrella
