Eosjs. How to add new key to JsSignatureProvider

Question

Here:

var privateKeys = [...];
var sp = new JsSignatureProvider(privateKeys);
var key = 'ASG...';
sp.addKey(key);  // (1)

I want to add new key to JsSignatureProvider, but I can't find method like (1). Is it exists?

How can we add new key to JsSignatureProvider after it already been constructed?

Thank you!

ps. We don't use JsSignatureProvider in production code. Just for testing.

You need to add public key to JsSignatureProvider.availableKeys (string[]) and private key to JsSignatureProvider.keys (Map<string,string>) by public key.

var { Numeric } = require('eosjs');
var { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig');
var ecc = require('eosjs-ecc');

var privateKeys = ['...'];
var sp = new JsSignatureProvider(privateKeys);
var key ='...';

const pub = Numeric.convertLegacyPublicKey(ecc.PrivateKey.fromString(key).toPublic().toString());
sp.keys.set(pub, key);
sp.availableKeys.push(pub);
