Your question is Design Feature for Existing Application. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You’ve been asked to add a new feature to an existing application that already has active users, established workflows, and technical constraints. The feature needs to solve a real user problem without disrupting current behavior, and you’ll need to work within the realities of the current codebase rather than starting from scratch.
How would you approach designing a new feature for an existing application?
