How would a sequence diagram specifically highlight a retry mechanism for an OTP validation request after an initial temporary failure?

A sequence diagram specifically highlights a retry mechanism for an OTP validation request after an initial temporary failure by visually representing the iterative re-attempts and conditional logic involved. A sequence diagram illustrates the interactions between objects or participants in a system over time, showing the order in which messages are sent and received. An OTP (One-Time Password) validation request typically involves a client sending a user-entered OTP to a backend service for verification. A retry mechanism is a system's ability to automatically re-attempt an operation that initially failed due to a temporary or transient condition, such as a network timeout or a brief service unavailability, as opposed to a permanent error like an incorrect OTP.
