How to sending commands/request on websocket?

[shasanka]

I have backend websockets which are as follows:

1. ws://localhost:4000/xydata : only to get the xy coordinates data
2. ws://localhost:4000/commands : to send different commands and get the reply
3. ws://localhost:4000/messages : to receive messages

My question how do I send commands on the websocket, if I am make seperate endpoints in the RTK query using the streaming example on the website will it create new websocket connection for each endpoints.
Here is my code :

export const api = createApi({
  reducerPath: "api",
  baseQuery: fetchBaseQuery({
    baseUrl: "ws://localhost:4000",
  }),
  endpoints: (build) => ({
    streamMessages: build.query({
      queryFn: () => ({ data: [] }),
      async onCacheEntryAdded(arg, { updateCachedData, cacheEntryRemoved }) {
        const ws = new WebSocket("ws://localhost:4000");

        ws.addEventListener("message", (event) => {
          const data = JSON.parse(event.data);
          updateCachedData((draft) => {
            // draft.splice(0, draft.length);
            // draft.push(JSON.parse(event.data));
            return data;
          });
        });

        // ws.addEventListener("open", () => {
        //   console.log("we are connected");
        // });

        await cacheEntryRemoved;
        ws.close();
      },
      extraOptions: { maxRetries: 10 },
    }),
  }),
});

export const { useStreamMessagesQuery } = api;

I understand that the basequery will be ignored as i have used queryFn for the query in my endpoint, but this one only gets the data.
What do i have to do if i have to send different comands to a specific websocket and then get their replies?
For example I would like to send commands like : 'get_configuration' , 'set_configuration','set_user' , to the websocket.
