How to ask users to sign an EIP712 structured message.
Signing an EIP712 structured message is similar to signing a message.
The object that can ask the user his approval is called a Signer, once we've created a Signer object we can use the Signer to sign the EIP712 message.
Function
//Creating the signer
venlyConnect.createSigner();
​
//Asking the signer to sign a message.
signer.signEip712({
    walletId: '<WALLET_ID>',
    secretType: '<BLOCKCHAIN>',
    data : <YOUR JSON STRUCTERED EIP712 DATA>
})
Example
const signer = venlyConnect.createSigner();
​
signer.signEip712({
    walletId: 'c8ec9954-fa1a-4682-9cf8-ef5c1015d1d1',
