How to use the indy-sdk.cryptoAuthDecrypt function in indy-sdk

exports.getVerinym = async function(poolHandle, From, fromWallet, fromDid, fromToKey, to, toWallet, toFromDid, toFromKey, role) {
    console.log(`\"${to}\" > Create and store in Wallet \"${to}\" new DID"`);

        'verkey': toKey
    });
    let authcryptedDidInfo = await indy.cryptoAuthCrypt(toWallet, toFromKey, fromToKey, Buffer.from(didInfoJson, 'utf8'));

    console.log(`\"${to}\" > Send authcrypted \"${to} DID info\" to ${From}`);

    console.log(`\"${From}\" > Authdecrypted \"${to} DID info\" from ${to}`);
    let [senderVerkey, authdecryptedDidInfo] =
        await indy.cryptoAuthDecrypt(fromWallet, fromToKey, Buffer.from(authcryptedDidInfo));
