I am trying to integrate sms otp login experience for an application that we are building. The end goal is to create an onchain federated keyless account in aptos with the help of the id token that auth0 returns. The requirement on aptos side is that, the idtoken should have an nonce claim in the payload.
I am aware that if I utilize the /authorize request, basically universal login experience allows me passing nonce params. But I dont want to do that. We have dedicated mobile number input and otp input screen and we want to use that.
/paswordless/start and /oauth/token endpoints ( authentication apis ) can help me do that, but I could not find any way of passing custom nonce which i would expect in my id token payload.
Is there any way I can achieve this or is following Universal Login Flow the only solution ?
Our app is in react native btw.
