Guidance on building a shared key

[EnriqueL8]

Hey all!

I'm trying to build an Elliptic-Curve Diffie–Hellman (ECDH) shared key given a private key and a public key using this babyjubjub package. As far as I understand I need to use the mul() function where the starting point is the public key and add the private key big.Int to build such shared key.

Would appreciate any recommendations and if it makes sense to have an API in this package to build a shared key. Thanks!
