Execute Program until specific amount of bytes has been returned on stdout, then terminate

Imagine I have the following program/script ./generate-infinite-byte-stream:

#!/bin/bash
echo -n 'hello'
sleep infinity

The infinite sleep command represents a network connection that may or may not deliver more data in the indefinite future that I am not interested in. I would like to have a program, let's call it take 5 that runs ./generate-infinite-byte-stream until it has output 5 bytes on stdout and then terminates it:

take 5 ./generate-infinite-byte-stream
# gives 'hello' and returns with exit code 0

Is there such a program or do I need to roll my own with popen()? The program take should also redirect stdin to the executed program. Note: head -c 5 does not do the right thing, because it does not terminate:

./generate-infinite-byte-stream | head -c 5
# this returns 'hello', but never terminates

Aside: The name Take is inspired by the https://reference.wolfram.com/language/ref/Take.html command which returns the first n elements of a list.
