Tuple question - Typescript

Hey guys i'm having trouble with syntax.

let's say in my program i've:

pub enum SomeEnum{X,Y(Pubkey, u64),Z(otherEnum)}pub enum otherEnum{A(u64),B(u64),...}

In my fe/tests

if i want to pass the X it would be - { x: {} },
if i wanted to pass Y it would be - {y:[payee.publicKey, new BN(amount)] }

if i want to pass Z how it would be ?

trying stuff like this but it not working hmm

 { z: { A: new BN(amount) } }
