Sign an EIP712 message

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
arkaneConnect.createSigner();
​
//Asking the signer to sign a message.
signer.signMessage({
    walletId: '<WALLET_ID>',
    secretType: '<BLOCKCHAIN>',
    data : "<YOUR JSON STRUCTERED EIP712 DATA>"
})
Example
const signer = arkaneConnect.createSigner();

signer.signMessage({
    walletId: 'c8ec9954-fa1a-4682-9cf8-ef5c1015d1d1',
    secretType: 'ETHEREUM',
    data : "I agree with terms and conditions"
})
