From your guide, we can import private key and get three address types: 1, 3 and bc1q.

I read that Electrum stopped its options to create new wallets with 1 and 3 address types. Could we do this in Console of Electrum?

Or if I want to have address types like 1 and 3, I have to create a wallet with Segwit addresses, then I import its private keys to have 1 and 3 address types?
