How to transfer minting revenues ?

[azerty120]

Hi !
I tried to transfert minting revenues from subject if I own their gold mine as overlord with this code :

if = {
            limit = {
                any_scope_building = {
                    is_building_type = building_gold_mine
                    country_ownership_fraction = {
                        target = scope:overlord
                        value  > 0.5
                    }
                }
            }
            add = {
                country_minting_transfer = 1
                second_country_gets_minting_transfer = no
                minting_transfer_based_on_second_country = yes
            }
        }

But look like "country_minting_transfer" doesn't exist as a variable.

Any idea on how to do it ?

Maybe by tracking the amount of minting the subject own and creating it for the overlord, but no idea how to do that.
