Functionality

• If no user is mentioned, the command defaults to showing the banner of the user who invoked it.
• The command sends an initial "searching" message with a loading emoji, then replaces it with an embed containing:
  • The user's banner image (1024x1024, dynamic format).
  • A title with customizable emojis.
  • A footer showing the requester's display name and avatar.
  • A timestamp.
• Supports both prefix-based (P or p) and slash command (/) inputs.
• If no valid user is found or the user has no banner, an error message is displayed.

Code Overview

The command is built using a Command class structure and handles both message-based and interaction-based (slash command) inputs. It uses:

• client.embed() to create a formatted embed.
• mention.fetch().then(user => user.bannerURL()) to fetch the user's banner.
• Language localization for messages and emojis.
• Error handling for cases where no user is mentioned or no banner is found.
