How to claim BTG from original fork?

I have some old wallets where I transferred the BTC after the BCH and BTG forks. I got my BCH using electron but I don’t know how to get the BTG.

I used electrum and it has a different derivation path from Trezor so I can’t import the seed and use that. Thanks

Electron is a port of Electrum wallet to use BCH, renamed “Electron.”

You can do the same with ElectrumG - that’s the port of Electrum for BTG.
