I can assure you there's no sarcasm in my post

You're linking to the Electrum SV Fork, I don't think that helps. The keyword is "sent to pubkey", and I can't import those read-only on Electrum. It
might work if I import the private key, but I don't dare do that on a hot wallet. So I can't use it.
Anyway, I downloaded bitcoin-sv-1.0.9-x86_64-linux-gnu.tar.gz, but it didn't work "out of the box". It turns out I need to manually create a .conf, which I did (following node.bitcoinsv.io/sv-node/installation/bitcoind). After that, it's running, but without GUI, I have no idea how to import a
pubkey which I can use to get the balance needed to sign an offline transaction.
