Pulsar (GO) functions, how to Ack and Nack?

[conor-nsurely]

Hello,

In Pulsar functions using the pulsar-function-go/pf library, what is the correct way to Ack or Nack messages?

pulsar-function-go/pf only seems to be able to create producers like so:

		pfctx, _ := pf.FromContext(ctx)

		// publish a message
		pfctx.NewOutputMessage()

How would I ack/nack the messages from the pulsar function?

Is this possbile? Or what is the correct approach?

Thank you in advance
