Using mother's claim without murdering her (CB modding)

[Gunthah]

Currently, if a woman has a claim to a title with agnatic law this claim cannot be pressed unless it is inherited by her son after she dies.

I'm trying to modify the claim CBs to allow for men whose mother has a claim on an agnatic title press "their claim" taking the place of their mother, without having to kill her to do so.

I have so far not been successful and wonder if anyone would know how to do this. This is what I've come up with:

other_claim = {
    name = CB_NAME_CLAIM
    war_name = WAR_NAME_OTHER_CLAIM
    sprite = 2
    truce_days = 3650
    hostile_against_others = yes
    can_ask_to_join_war = no

    press_claim = yes
   
    allowed_to_target_tributaries = no

    infamy_modifier = 0.5
   
    sort_priority = 900

    can_use = {
        ROOT = {
            mercenary = no
        }
    }

    can_use_gui = {
        check_if_crusader_trigger = yes
    }

    can_use_title = {
        OR = {
            ROOT = { is_female = no }
            AND = {
                NOT = { ROOT = { religion_group = muslim } }
                NOT = { ROOT = { has_religion_feature = religion_patriarchal } }
                NOT = { succ_law_title = { has_law = agnatic_succession } }
            }
        }
        OR = {
            ROOT = { is_female = yes }
            AND = {
                NOT = { ROOT = { has_religion_feature = religion_matriarchal } }
                NOT = { succ_law_title = { has_law = enatic_succession } }
            }
        }
