When you’re guiding someone through adding an app to Slack, clarity matters. Use 💻➕🔔 to highlight desktop notifications, or ➕📱🔧 to focus on mobile setup. A combo like 🔗📲✨ signals a smooth integration, while 📥📲🔧 points to downloading and configuring. These combos fit well in quick how-to messages or onboarding chats where you want to keep instructions concise and clear.
