Generates a direct KYC verification link for an existing user. Redirect the user to this link to complete identity verification with the KYC provider.

Important Notes

The user must be created first via Create User.
Each kycLink is tied to a unique session. If expired, generate a new link.
If partnerRedirectUri is not provided, the user may not be redirected after completing KYC.
Supports both HTTPS and custom mobile URI schemes (e.g., myapp://).

Use Cases

Initiate KYC: Redirect the user to complete identity verification after account creation.
Email or app link: Embed the kycLink in an onboarding email or app screen.
Custom redirect: Use partnerRedirectUri to bring the user back to your app after verification.
