Modifier to grant Units on War declaration

[Aldollin]

does anyone have an idea if its possible/how to make a modifier that grants free units whenever you are targeted my by a declaration of war ?(similar to the australia production bonus)

i looked at the australia example, and its using this dynamic modifier:
MODIFIER_PLAYER_ADD_DIPLOMATIC_YIELD_MODIFIER
(has the effect EFFECT_ADD_DIPLOMATIC_YIELD_MODIFIER)

from that example i assume you can only use that one to modify city yields, not something like grant units

maybe something with pseudoyields? havent fully understood how to use these

any ideas/advice are appreciated

May or may not be more that I missed from a quick seek/find. You would probably need to build your own modifier and spec the effect of the modifier, it's requirements, and other stuff, like they do here by creating a modifier for the Colossus Wonder

		<Row>
			<ModifierId>COLOSSUS_GRANT_TRADER</ModifierId>
			<ModifierType>MODIFIER_SINGLE_CITY_GRANT_UNIT_IN_CITY</ModifierType>
			<RunOnce>true</RunOnce>
			<Permanent>true</Permanent>
		</Row>

But I am not sure how you create by using Modifiers and Effects the "trigger" for firing the MODIFIER_SINGLE_CITY_GRANT_UNIT_IN_CITY or MODIFIER_SINGLE_CITY_GRANT_UNIT_IN_NEAREST_CITY from being the victim of a declaration of war

<Row>
<ModifierId>TRAIT_CITADELCIVILIZATION_DEFENSIVE_PRODUCTION</ModifierId>
<ModifierType>MODIFIER_PLAYER_ADD_DIPLOMATIC_YIELD_MODIFIER</ModifierType>
</Row>

the only way i can think of using Modifiers and Effects is maybe with the Effect/Modifier from australia:
the Modifier gets 4 arguments:

<Row>
<ModifierId>TRAIT_CITADELCIVILIZATION_DEFENSIVE_PRODUCTION</ModifierId>
<Name>DiplomaticYieldSource</Name>
<Value>WAR_DECLARATION_RECEIVED</Value>
</Row>
<Row>
<ModifierId>TRAIT_CITADELCIVILIZATION_DEFENSIVE_PRODUCTION</ModifierId>
<Name>TurnsActive</Name>
<Value>10</Value>
</Row>
<Row>
<ModifierId>TRAIT_CITADELCIVILIZATION_DEFENSIVE_PRODUCTION</ModifierId>
<Name>YieldType</Name>
<Value>YIELD_PRODUCTION</Value>
</Row>
<Row>
<ModifierId>TRAIT_CITADELCIVILIZATION_DEFENSIVE_PRODUCTION</ModifierId>
<Name>Amount</Name>
<Value>100</Value>
</Row>

now i wonder if the effect this modifier uses could also take something different as an argument, so you could use it to apply a modifier
similar to how religious beliefs have modifiers that attach modifiers as their effect
