How to publish a View to Slack app for all users?

I have a Slack App that is connected to an AWS Lex bot. Thus, the Request URL for the Slack app is the Postback URL provided by Lex. However, I want to add a Home tab for the app, but am unable to publish a surface for all users. The Slack API only seems to allow you to publish a surface for a specific user (user_id is a required parameter for the POST call). How can I publish this view to all users who use the app?

publish_url = ""
header = {'content-type':'application/json'}
parameters = {
    "token": slack_token,
    "user_id": member_id,      # <--- This is my problem
    "view": json.dumps({
        "type": "home",
        "blocks": [
                "type": "section",
                "text": {
                    "type": "mrkdwn",
                    "text": "Welcome to *Survey Analyzer*! ..."
r =, params=parameters, headers=header)

When I use my own member ID, it pushes the view properly to me and me only. I've also tried using the app's ID, but that doesn't seem to push the view to any users.
