You cannot restore seed phrases on Trezor using Electrum. You can only restore the seed phrase on Trezor via Trezor Suite.
This is not true.
You can restore seed phrase on any wallet that supports BIP39, including Electrum, but it's not recommended to restore seed phrase from cold to hot wallets.
Only problem in this case can be different derivation paths for some wallets that are not standard, or maybe accounts had additional passphrases.
