Golang中的struct通用图

I have 2 types of struct based on 3rdparties code that I cant change

type AddEvent struct {
}

type DeleteEvent struct {
}

I would like to create a map of string as key and Object as value so each time I got new event I will add it to the map I.E Map should look like this:

EventMap:
    event1,AddEvent{}
    event2,AddEvent{}
    event2,DeleteEvent{}

The issue that AddEvent and DeleteEvent are not defined as interfaces.
Is there I way to create a generic map in go using any struct as a value and in case yes, how can I read it do I need to check the type using reflect

I.E
event:=EventMap[event1]
if reflect.TypeOf(event)==AddEvent{
}else if reflect.TypeOf(event)==DeleteEvent{
}

    what comment says looks good, but missing type switch. Full version maybe you need is:

    m := make(map[string]interface{})
    addEvent := new(AddEvent)
    m["event1"] = addEvent
    switch m["event1"].(type) {
    case *AddEvent:
        // do something
    case *DeleteEvent:
        // do other things
    }
