I document the config.toml option in 16fc6a2 but left that segment of the configuration file commented-out. The reason for keeping this option a bit hidden is that it may be a source of misconfiguration. In particular, we don't validate the string in any way, and I suspect it should be a bech32-valid account identifier, but unclear how (if) we can validate that on Hermes side.
Currently, using a random string such as fee_granter = 'adi' will yield a very obscure error message (see below). Will open an issue to track this.
