Here's a Slack "App Manifest" to make adding the user token scopes easier

[Efresia]

Thank you for this fantastic tool. Here's an "App Manifest" template can be pasted into the app manifest section of the slack UI, just change the name to match the name you used when you created the "app". The duplicate scopes are commented out so it works as-is. You can of course paste just a section as well.
