Add "Convert" scope to Sign In With Coinbase

The ability to convert between USDC and USD (1:1, no fees) is a pretty important feature in Coinbase. Currently, you can do this using the Advanced Trade APIs (Create Convert Quote and Commit Convert Trade). However, I don’t believe there is a way to enable these scopes with Sign In With Coinbase. Can you add these scopes, please? The added functionality would be very helpful.
