The fastest way to send new data from a simple node js script (telegram, slack or another bot?)

I want to send data that my script generates.

I want there to be virtually no delay ?

What is best for this and what is also relatively easy to implement?

Telegram has a delay of about a (1-3) second , I do not know how the others like slack, discord ?
Or maybe email will be much better and for example sending it via SNS on aws ?

Or maybe something else?

My first question is, send data to where?
