Can you use one conn to subscribe multiple currency pairs?

[iwanami10]

README says "it is recommended to use one conn to initialize multiple channels"

But, is it possible to subscribe multiple currency pairs (eg. BTC_USDT and ETH_USDT) to SpotPublicTradeChannel with only one Connection?
I subscribe two pairs and the former callback does not called.
Using two Connections solved.

This is an example of using SpotPublicTradeChannel to subscribe to multiple currency pairs, which you can refer to

import asyncio
import logging

from gate_ws import Configuration, Connection, WebSocketResponse
from gate_ws.spot import SpotPublicTradeChannel

logger = logging.getLogger(__name__)

async def callback(conn: Connection, response: WebSocketResponse):
    if response.error:
        conn.close()
        raise response.error

    result = response.result
    logger.debug("received update: %s", result)
    assert isinstance(result, dict)


if __name__ == "__main__":
    logging.basicConfig(level=logging.DEBUG, format="%(asctime)s: %(message)s")
    cfg = Configuration()
    cfg.verify = False
    cfg.host = "wss://api.gateio.ws/ws/v4/"

    conn = Connection(cfg)
    channel = SpotPublicTradeChannel(conn, callback)
    channel.subscribe(["BTC_USDT"])
    channel.subscribe(["ETH_USDT"])

    loop = asyncio.get_event_loop()
    loop.create_task(conn.run())

    try:
        loop.run_forever()
    except KeyboardInterrupt:
        tasks = asyncio.Task.all_tasks(loop)
        for task in tasks:
            task.cancel()
        group = asyncio.gather(*tasks, return_exceptions=True)
        loop.run_until_complete(group)
        loop.close()

Actually, I tried to change local_order book.py to deal with multiple currency pairs.
But, your code worked correctly and I noticed SpotOrderBookChannel (not SpotOrderBook"Update"Channel) was enough for me.
It solved. Thank you.
