send message from bot to direct message after typing /slash command

Question

I'm trying to make SlackBot and if I call him in some public channel it works fine but when I call him (type slash-command) in any direct channel I receive "The server responded with: {'ok': False, 'error': 'channel_not_found'}". In public channels where I've invited my bot it works fine, but if I type "/my-command" in any DM-channel I receive response in separate DM-channel with my bot. I expect to receive these responses in that DM-channel where I type the command. Here is some part of my code:

if slack_command("/command"):
    self.open_quick_actions_message(user_id, channel_id)
    return Response(status=status.HTTP_200_OK)

def open_quick_actions_message(self, user, channel):
    """
        Opens message with quick actions.
    """
    slack_template = ActionsMessage()
    message = slack_template.get_quick_actions_payload(user=user)
    client.chat_postEphemeral(channel=channel, user=user, **message)

Here are my Event Eubscriptions

Here are my Bot Token Scopes

Can anybody help me to solve this?

I've already solved my problem. Maybe it will help someone in the future. I've sent my payload as the immediate response as it was shown in the docs and the response_type by default is set to ephemeral.

The part of my code looks like this now:

if slack_command("/command"):
    res = self.slack_template.get_quick_actions_payload(user_id)
    return Response(data=res, status=status.HTTP_200_OK)
else:
    res = {"text": "Sorry, slash command didn't match. Please try again."}
    return Response(data=res, status=status.HTTP_200_OK)

Also I have an action-button and there I need to receive some response too. For this I used the response_url, here are the docs, and the requests library.

Part of this code is here:

if action.get("action_id", None) == "personal_settings_action":
    self.open_personal_settings_message(response_url)

def open_personal_settings_message(self, response_url):
    """
        Opens message with personal settings.
    """
    message = self.slack_template.get_personal_settings_payload()
    response = requests.post(f"{response_url}", data=json.dumps(message))
    try:
        response.raise_for_status()
    except Exception as e:
        log.error(f"personal settings message error: {e}")

P. S. It was my first question and first answer on StackOverflow, so don't judge me harshly.
