Configure native messaging blocklist

Setting the policy specifies which native messaging hosts shouldn't be loaded. A deny list value of * means all native messaging hosts are denied, unless they're explicitly allowed.

Leaving the policy unset means Google Chrome loads all installed native messaging hosts.

Example value:

com.native.messaging.host.name1
com.native.messaging.host.name2

Names of the forbidden native messaging hosts (or * for all)
