Use "First Time" Property: Mixpanel automatically adds a "First Time" property to every event. This property is true if the event is the first time a user has performed that specific action. You can use this in conjunction with your "new users" event to identify new users.

OR create a cohort for those users

Set a "User Created Date" Property: When a user first signs up, send a $set call to Mixpanel's API to add a "User Created Date" property to their profile.

Filter by "User Created Date": You can then filter users based on this property to identify those who were created within a specific time frame (e.g., new users this week).

introduce an event like "new users" that records the user profiles/ ids per MIN (user created date)

then you just need to simply select that event, and count distinct the "new users" per month
