How to make an Event in wc 4

Does anyone know how to add events and actions in WC4? Like the mod 'The Great Patriotic War' by The Conqueror (im loved this mod) which has events such as when Warsaw is captured, Soviets will become enemies of the Axis, and when Paris is captured, France will surrender, and Australia declare the war to Japan at turn 9th.  Its would be interesting to make an event trigger just one map like HOI4, Maybe we can start by explaining the meaning and how to fill in the binary/hex below?

"Action 16": {



"0x0": "ID",

"0x4": "EndEvent",

"0x8": "Round",

"0x1C": "Coordinate"

},

-------END-----
CC 9F(ID)                   00 00(0,Related event) 00 CC                      CC CC

0A 00(triggercond)      00 00                          0B 00(triggereffect)  00 00

04 00(camp)               00 00                          02 00(countryID)     00 00

00 00                         00 00                          02 00                      00 00

00 00(triggerround)     00 00                          00 00(eventID)        00 00

00 00(OwnerID)          00 00



"Event 44": {



"0x0": "ID",

"0x4": "RelatedEvent",

"0x8": "TriggerCondition",

"0xC": "TriggerEffect",

"0x10": "Camp",

"0x14": "CountryId",

"0x20": "TriggerRound",

"0x24": "EventId",

"0x28": "OwnerCountry"

},
