have shared data for different client with same connection parameters

If creating 2 Redis clients with same connection parameters, I would like to have shared data between them

const Redis = require('ioredis-mock');
const client1 = new Redis('localhost', 6378);
const client2 = new Redis('localhost', 6378);
await client1.hset('testing', 'test', '2');
const val = await client2.hget('testing', 'test');
console.log(val) // should output 2

As I see it, it can be implemented by mapping connection string to a DB object

how about a feature like this:

const Redis = require('ioredis-mock');
const client1 = new Redis();
const client2 = client1.createConnectedClient();
await client1.hset('testing', 'test', '2');
const val = await client2.hget('testing', 'test');
console.log(val) // should output 2
