Does hermes config auto --chains support testnets?

Context

I'm trying to auto-generate hermes config for a connection between Cosmos Hub and a Celestia testnet.

Problem

$ hermes config auto --chains cosmoshub testnets/celestiatestnet --output $HOME/.hermes/config.toml
2023-09-15T13:20:07.201428Z  INFO ThreadId(01) using default configuration from '/Users/rootulp/.hermes/config.toml'
2023-09-15T13:20:07.207531Z  INFO ThreadId(01) running Hermes v1.6.0+1c1cf02
2023-09-15T13:20:15.645009Z  WARN ThreadId(01) No key found for chain: cosmoshub-4
SUCCESS Config file written successfully at '/Users/rootulp/.hermes/config.toml'.
                        However, configurations for the following chains were not able to be generated: {"testnets/celestiatestnet"}

However https://github.com/cosmos/chain-registry/blob/master/testnets/celestiatestnet/chain.json exists.

Question

Does the hermes config auto --chains support testnets? It doesn't specify in hermes help config output.
