Electrum generates seed phrases different from the BIP39 standard, so only Electrum and some wallets like Sparrow wallet and bluewallet provide support for the electrum seed phrase standard.
As far as I know, the only wallet that supports electrum seed phrase is bluewallet.
If you want to import your electrum wallet to Sparrow, you have to import the wallet file. You can't import the seed phrase that has been generated by electrum to Sparrow.
