# To do more operations on this node, we can do this in two ways:
# - We can use the Nim Node API, which is currently not exposed
# - We can use JSON RPC

# TODO Subscribe and publish to topic via Node API
# Requires https://github.com/status-im/nim-waku/issues/53

# Here's how to do it with JSON RPC

# Get RPC call signatures in Nim

# TODO Use publish as well
