I am trying to apply the coinbase wallet API with oauth to use its send functionality. I have been able to connect to the API and use its endpoints, but whenever I try to use the send functionality, I am thrown the error Invalid amount for meta[send_limit_amount]. My omniauth initializer looks like this:

provider :coinbase, , ENV['CLIENT_ID'], ENV['CLIENT_SECRET'], 
scope: 'wallet:user:read wallet:user:email wallet:accounts:read wallet:transactions:send'

The reason for this error is because, in order to use the send functionality, coinbase requires additional parameter meta[send_limit_amount]. Where and how am I supposed to apply this additional scope?
