// 1. Creates an identity using createIdentity
// 2. Creates a proof using createProof
// 3. Calls the register function on the RLN contract, with the proof that was generated
// !!!NOTE!!!
// Interep has not updated their verifiers, so the proof generated by createProof will not work :( Have raised the issue with their team
