1. Generate a keypair with `secp256k1_keypair_create` and obtain the xonly public key with `secp256k1_keypair_xonly_pub`.
2. Call `secp256k1_musig_pubkey_agg` with the xonly pubkeys of all participants.

4. Generate a pair of secret and public nonce with `secp256k1_musig_nonce_gen` and send the public nonce to the other signers.
5. Someone (not necessarily the signer) aggregates the public nonce with `secp256k1_musig_nonce_agg` and sends it to the signers.
6. Process the aggregate nonce with `secp256k1_musig_nonce_process`.
