Hi Asaf, Weiyi here from the Mixpanel support team. Thanks for reaching out. Jumping right into your question, it sounds like you will need to set up the Make's Mixpanel integration. I see that Make has provided documentation on how to set this up at this link.
Once the integration is connected, it seems that there is a "track event" module (Link) which would track an event into your Mixpanel project.
If you have any questions about setting this up on the Mixpanel side(e.g. where to get your Mixpanel credentials, how to create a Mixpanel service account, etc), feel free to reach out here. I will do my best to assist. For anything on the Make side of the integration, I recommend contacting the Make team instead.
I hope this helps.
Best,
