Send a dm to user after bot/app has been added/authorized? (user install)

I would like the process of adding my bot to go something like this:
  1. Lets say I send the bot authorization link to one of my friends, to showcase it (https://discord.com/oauth2/authorize?client_id=xxxxxx)
  2. They click on the link and authorize it, and upon getting back to Discord they will receive a DM like:
    Hello and thank you for adding this bot, with this bot you can check the weather in any country you wish! Using these simple commands:
/help - will give you this message
/weather <country code> - displays that country's current weather
/weather <country code> <date> - displays that country's weather at that date and time
/etc
  3. And then they can execute those commands as they wish.
How could I achieve this? Does there exist a call that happens when a user authorizes the bot? My initial thought was that this does not exist, but maybe I could use oauth redirects, however I ran into problems there too.

https://discord.com/oauth2/authorize?client_id=xxxx&response_type=code&redirect_uri=https%3A%2F%2Fexample.com&integration_type=1&scope=applications.commands

This link redirects correctly, with a code that looks like this "Mz9AVQsPphK3uqdTZcxUL2kJaEDH46", I am not quite sure what to do with it, but either way, when response_type is "code", the app actually doesn't get authorized.

https://discord.com/oauth2/authorize?client_id=xxxx&response_type=token&redirect_uri=https%3A%2F%2Fexample.com&integration_type=1&scope=applications.commands

However if the response type is "token", redirection works, and the app does actually get authorized, but from my understanding it is limited to 7 days. In my case this might be alright though.

So now after redirecting, I can get the access_token, and in theory, if I also add the identify scope, I should be able to get user information with the Discord API. However this returns message 401. Having the identify scope alone works fine, however together with applications.commands. Doesn't work.
