Is there any example to show how we can trigger the ecc calculation method using Nitrokey 3?

Nitrokeys FIDO2 / Nitrokey 3
1

I am working on a MPC project would like to use Nitrokey 3 as the secret.
May I know if there is any example that I can refer to so that I can use secp256k1_add, secp256k1_sub function in the Nitrokey 3?

Thanks.
