Configure a list of origins that grant an extended background lifetime to connecting extensions.

Extensions that connect to one of these origins keep running as long as the port is connected.
If unset, the policy's default values are used. These are the app origins that offer software development kits (SDKs) that are known to not offer the possibility of restarting a closed connection to a previous state:
- Smart Card Connector
- Citrix Receiver (stable, beta, back-up)
- VMware Horizon (stable, beta)

If set, the default value list is extended with the newly configured values. The defaults and policy-provided entries grant the exception to the connecting extensions as long as the port is connected.

Example value:

chrome-extension://abcdefghijklmnopabcdefghijklmnop/
chrome-extension://bcdefghijklmnopabcdefghijklmnopa/
