I found this famous message, which came from an old coin holder (2011 address, held ~$300M worth of BTC in 2017) in a matter of public interest.I would like to independently verify it. How do I do that with Electrum?Message (2 lines, no extra line breaks at the end):Address 16cou7Ht6WjTzuFyDBnht9hmvXytg6XdVT does not belong to Satoshi or to Craig Wright.Craig is a liar and a fraud.Address:16cou7Ht6WjTzuFyDBnht9hmvXytg6XdVTSignature:G39S6i4XsfQnixN5ePMjVPboWvGXdnW8xFFAXiwEriZFCclflbD7umP58u3Sl+dvvXC5BxBrRNkTMNf92O1UIXw=
