If I add permissions to my app after I had generated the access token do I need to generate a new access token? And if so, how do I do that? There does not seem to be a button to regenerate the token.

Adding a scope to your app via the App Console does not retroactively grant that scope to existing access tokens.
That being the case, to make any API calls that require that scope, you'll need to get a new access token with that scope.
You can retrieve a new access token the same way as you would have originally, either using the "Generate" button on the app's page on the App Console, or via the OAuth app authorization flow.
