I just created a wallet on electrum then i copy paste the seed on wasabi wallet in order to recover it but it gives me acess to another wallet not the electrum wallet.
This may be a bit late but this should not have happened. You are either using an old version of Electrum (in which case you should upgrade) or Wassabi wallet has a bug because Electrum seed (as it was mentioned are not BIP39) are generated in a way that they will not be a valid BIP39 mnemonic and should be rejected by wallets validating such seed phrases!
You can see it in the code where it avoids creating BIP39 valid mnemonics:
