How to sequentially publish messages in pubnub?

So the question is how to send messages in pubnub sequentially.

Example: I add text and 2 images. Flow should be like => send text as 1st message, send first image as 2nd message and send second image as 3nd message. They should appear in pubnub history one by one.

Let`s say I have all this stuff in sendArray variable

(async () => {
  for await (const item of sendArray) {
    pubnub.publish({ 
      channel: currentChannel, 
      message: item, 
    })
  }
})();

I`ve tried something like this, but it's not working.

This is almost correct, just a wrong placement of the await keyword.

(async () => {
  for (const item of sendArray) {
    await pubnub.publish({ 
      channel: currentChannel, 
      message: item, 
    })
  }
})();

This is because the publish method is an async operation that you need to await. for await is a special construct for iterating async iterables so there is no need to use it here. For loop respects the await keyword inside async blocks.
