How to use:
Create a campaign to send a push notification to a specific user or a segment of users.

• Target Segment/User ID: To target a single user, enter user_USERID (e.g., user_abc123). To target a segment, use field=value (e.g., gender=male or location=NY). You can combine filters with commas (e.g., gender=male,location=NY).
• After creating a campaign, you can view it in the list below. (Push notification sending is simulated in this demo.)
