I am just adding a little information. To my knowledge, for reasons of 'safety standards,' the seed produced by Electrum can only be used in Electrum, and the seed is different from BIP39 seeds in general.

You can try checking the electrum seed at https://iancoleman.io/bip39/ then the results will be invalid.
However, when creating a new wallet, you can choose the BIP39 seed option to import seed from other wallets that using the BIP39 algorithm (such as Mycelium, Ledger, etc.)

So as long as you have a seed or private key from Electrum, then you can still access your Bitcoin even though from Electrum Wallet on other devices.
