How to display values ​​from the filter in the admin panel?

Question

Django

The essence of this is that I have a participant model and an event model attached to it to which the participant is subscribed. In the admin panel, you need to display the participant's name, surname, event and date of registration. There is a list_filter in the admin panel for events on which participants are subscribed. Can you please tell me how to display exactly the event that I choose in the filter?
