I think you need to know what seed is and never get confused about it. From seed phrase, the seed is created. From the seed, the extented private key is created. The extended private key can be imported, it is recognized as the master private key on Electrum (airgapped cold storage for offline use) , but you will have to specify the derivation path for the extended private key, which can be BIP44, BIP49 and BIP84.

You can use this tool, Mnemonic Code Converter to derive anything you also want to derive. You can make use of the seed phrase (generally for all the derivation path), the seed, (generally for all the derivation path), BIP32 Root Key (specific to extended private key) to derive the extended private key (specific to address type) to generate child keys and addresses.

Note: use it offline, downloading its html file is the best and run it on airgapped device.
