Electrum does not generate bip39 seed phrases. So, you can only recover your electrum seed phrase using electrum.
I think I started to remember smth. I could generate an electrum seed fraze. Then when restoring selected Bip39 "to check compatibility", ignoring "bip39 checksum failed". Electrum allowes that. (I didn't know it altered adresses). Then probably changed smth in derivation path.
The question is how do I check all derivation paths, knowing seed fraze and 2 adresses.
Firstly make sure that the address in which the bitcoin is present starts with bc1 on the bitcoin block explorer.
Then while entering the seed phrase in the electrum wallet, select native segwit.
Try using detect exisiting accounts option and wait for some time to sync the wallet and then verify the address tab for your addresses.
If that does not work then try manually testing different derivation paths and keep checking the addresses tab.
