Hi, i have created my own private key, public key and seed phrase.

But i can't see the option to add a seed phrase to my private key.
When i created my wallet it asks you to set a type of address and the private key, i created a bech32 address with the private key successfully.

Is there a way to add my seed phrase to that private key?

If i start a new wallet and use the seed phrase i have instead, can i make it bech32?
