I was testing this wallet/DEX and unfortunately their Bitcoin/LN wallet which provides a BIP39 seed currently doesn't allow setting custom fees for on-chain transactions. Restoring the seed in a more powerful wallet was challenging since apparently they provide bech32 addresses but they use a non-standard derivation path for them: m/44'/0'/0'
It's undocumented, I've found the information from a discussion on their Discord.
