Configure native messaging block list

Specifies which native messaging hosts that shouldn't be used.

Use '*' to block all native messaging hosts unless they are explicitly listed in the allow list.

If you don't configure this policy, Microsoft Edge will load all installed native messaging hosts.

Example value:

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