Keeps saying insufficient network fee for Defi Wallet Earn

I've been trying to put some USDC into Defi wallet's new earn function, but it keeps telling me I don't have enough ETH network fee, despite already having some ETH in the Defi wallet already. So: 1. How much ETH does it cost to put money in earn? I tried to look for it everywhere but couldn't find a consistent answer 2. I have about $50 CAD worth of ETH in my Defi wallet, but it's still not enough? Thanks in advance. PS. Located in Canada
