+ * or [`cltv_expiry_delta`]) has a [`BroadcastChannelUpdate`] event message generated
+ * containing the new [`ChannelUpdate`] message which should be broadcast to the network.
+ *
+ * Returns [`ChannelUnavailable`] when a channel is not found or an incorrect
+ * `counterparty_node_id` is provided.
+ *
+ * Returns [`APIMisuseError`] when a [`cltv_expiry_delta`] update is to be applied with a value
+ * below [`MIN_CLTV_EXPIRY_DELTA`].
+ *
+ * If an error is returned, none of the updates should be considered applied.
