Paying with Satisfaction Points

Hi! I'm trying to make a mod to exchange different types of points you can collect in the game. I have an interaction that I added a payment to:

<L n="basic_extras">

<V t="payment">

<Un="payment">

<V n="payment" t="literal">

<Un="literal">

<V n="payment_cost" t="amount">

<Un="amount">

<T n="amount">11</T>

</U>

</V>

<V n="payment_source" t="bucks">

<Un="bucks">

<E n="bucks_type">SatisfactionPoints</E>

</U>

</V>

</U>

</V>

</U>

</V>


But the "SatisfactionPoints" command doesn't work. Maybe you know what they are called in coding?
