Regarding Oberon in SDK13

Hi. I'm using nRF52832, SDK13.0.0.

I need to use ECDH curve25519.

I just realized that Oberon has 25519.

There is Oneron library in ble_app_eddystone example.

I think, ECDH25519 needs generating Private and Public keys(like nrf_crypto_ecc_key_pair_generate).

Then compute function like nrf_crypto_ecdh_shared_secret_compute.

I think, I've found function for generating key.

es_beacon_ecdh_pair_generate() function in es_security.c is the function for generation key. Right?

But I can't find the function for compute.

Could you please help me?
