Implement a feature on the client dashboard that enables clients to conduct and manage giveaways, including the selection of winners. This tool will allow clients to set up a giveaway linked to their engagements, define entry criteria, and randomly select a winner from eligible participants. The system should ensure fairness and transparency in the selection process. Additionally, it could provide options to announce the winner directly through the platform or generate a notification to inform the winner. This feature aims to add an interactive and rewarding element to engagements, encouraging participation and boosting user interest.
