When a Sales rep clicks a button on an opportunity, a simple discount calculator screen should be launched. Which automation tool should an administrator use to build this discount calculator screen?

Flow Builder supports screen flows with interactive UI elements such as input fields and formulas, and a screen flow can be embedded in a button or quick action on any record page, making it ideal for a user-triggered calculator experience.

Workflow Rules execute background logic automatically based on criteria and do not support building or displaying interactive screens to users.

Platform Events are used for event-driven, real-time messaging between systems and have no capability to present an interactive UI screen to a user.

Process Builder automates background record-based actions and does not support launching interactive screens or calculator-style user interfaces.
