The document states you either need to upgrade or make registry changes:-

• Cisco AnyConnect with Umbrella roaming module: Version 4.8.02042+ (link)
  OR
• Using older client version, configure TLS 1.2 use with changes to the Windows Registry with these steps.

I suggest you upgrade your current version to the latest version, which is currently 4.9
