Customize calendar events

Good morning:
I would like to know how I can make each user have their own calendar with their own events.

I explain:

I have the calendar and the inputs so that the users logged in with their accounts create the events, but regardless of which user is logged in, the calendar shows the same events for everyone. How could I make each user who logs in with their account see their personalized events appear on the calendar? Thank you

PS: I use the Full Calendar plugin
