So yeah, my intention was to use the seed phrase and private key that script created. Because if i just import a seed phrase alone into Electrum. Electrum is creating the private key with it's own method.
If you import a BIP39 seed phrase in electrum, it doesn't use
its own method for genrating your private keys. Electrum uses a standard algorithm to generate the private keys.
What i did was to use the Private key of my script to use Electrum, but when i do that, there is no seed phrase, in case i want to recover my wallet with the seed phrase.
You generated a private key from a random number. So, you have a private key, not a seed phrase.
If you want to have a seed phrase, you should generate a seed phrase.
Take note that you can derive private key from a seed phrase, but you can't derive seed phrase from a private key.
