I use remix and deployed both contracts (token and dex) on rinkeby. I have changed the address of the fWETH contract in the dex contract and I have fWETH tokens in my wallet. I don't see any approve function. Is this not needed?

token contract: 0x30fF03d611CE2C4ba7942f8c2ea17385218F522e
dex contract: 0xf5bcCca9c8c76d1c9844776e7FCD6f9464C2A632

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
