API to get a list of events to participate in Rails

I would like to create an API for displaying a list of events that a particular user participates in on the user information screen in an application that has the following function of Rails.
I think the list of events created by the user can be obtained by current_user.events.all, but what method should I use to obtain the list of events that a particular user participates in?
Also, I would appreciate it if you could let me know if there are any best practices for creating an event management app with a follow-up function!

User has_many: events (user as event creator)
Event has_many:users,through::participations
Model definitions are as shown in .
