So the following code does work as i want, but i don't think this is the way it should be done.

I edited the event to this:

@events.register(
    events.NewMessage(
        incoming=True,  # I removed the (from_users) argument
    )
)
async def message_received(event):
    """This function will be called when a new message comes from the defined channels

    Args:
    event (_type_): Event containing information about the message
    """

    incoming_message_text = event.message.message

    # We use try block here as we are going to get (channel_id) for all incoming messages
    # because we are getting all incoming chats, this also includes users
    # which don't have (channel_id) so an exception occurs
    try:
        sender_id = (await event.get_input_sender()).channel_id

        if sender_id == desired_channel_id:
            print(f"Message from {sender_id}:\n{incoming_message_text}")
    # If Sender is NOT a channel, this exception occurs, we ignore it
    except AttributeError as e:
        print(e)

This is a hacky/inefficient way of getting the job done and i accept it, yet i don't know the correct way.

Until someone responds with a better answer, others facing this issue can use this hack at least.
