Cisco IOS XE 16.8 gRPC Dial Out examples

[Hawkeye148]

I am looking if there are any examples of setting up a gRPC dial out subscription for CSR1000v that is available for setting up a gRPC dial-out config for IOS XE 16.8. From my understanding the only possible option as for now is creating using an external IETF client to extract information.
