Discord DM Deletion Automation

I need a solution to delete Discord direct messages on my iOS device for both sides for me of the conversation, involving 20–24 users. I'm open to using an automated script or bot that runs on my iOS device.

Ideal Skills and Experience:
- Familiarity with Discord API
- Experience creating scripts or bots for iOS
- Knowledge of automation tools for iOS

Please provide a method that works effectively, whether it's message deletion, conversation removal, or any other approach.
