urequest and timeout / iteration over results

[pn2new]

I am trying to interface to ntfy.sh. Posting messages works, but I struggle polling/receiving messages from the server.
One way to achieve this would be, following examples:

resp = urequests.get(f"https://ntfy.sh/{TOPIC}/json", stream=True)
for line in resp.iter_lines():
    if line:
        print(line)

However, micropython's built-in urequest seems not to allow to iterate over the lines received.

When I access the server from the command line using curl, like this

  curl -s "https://ntfy.sh/TOPIC/json?since=60m"

the messages are indeed shown, but the request does not "end". This seems to be by design, so that one keeps the connection open and receives the messages as they arrive.

What would be the best way to implement this in micropython? Is there a way to do this using the internal urequest, or do I need to used another library / other code?
