I followed this YT video which explains exactly how to do this using Electrum.

But when I paste my btc addresses from my electrum wallet I receive from the byteball bot: 'P2PKH addresses are supported'. Is there a way to get around this in this in the Electrum wallet?

(By the way do not try to use coinbase for this function. You will still find videos explaining how to digitally sign your btc with coinbase but they have disabled this function for a long time now.)
