Unable to send self-message using broadcast

My expo app that uses supabase for authentication. I wanted to give broadcast feature a try but unable to send self-message. terminal logs: ⁨``` LOG STATUS CHANNEL_ERROR LOG STATUS SUBSCRIBED LOG response ok

⁨```
import { View, Text } from "react-native";
import { supabase } from "@utils/supabase";
export default function Home() {
useEffect(() => {
    const myChannel = supabase.channel('room-2', {
      config: { broadcast: { self: true } }
    })
    myChannel.on(
      'broadcast',
      { event: 'test-my-messages' },
      (payload) => console.log(payload)
    )
    myChannel.subscribe((status) => {
      console.log("STATUS", status)
      if (status !== 'SUBSCRIBED') { return }
      myChannel.send({
        type: 'broadcast',
        event: 'test-my-messages',
        payload: { message: 'talking to myself' }
      }).then(response => console.log('response', response))
    })
  }, [])

  return (
    <View>
      <Text>Home</Text>
    </View
  )
}
