How to use BetterTouchTool to show Mail.app unread count in touch bar

Question

I have a MacBook Pro with a touch bar and have never used BetterTouchTool. I know it has touch bar functionality, like adding a button to open an app. Is it possible to show either of the following?

• The Mail.app icon (with unread email count)
• Just the number of unread emails

If so, how can it be accomplished?

Answer 1

BetterTouchTool has a "widget" option for the touch bar, and one of the options is to display the output of an AppleScript program. You could write a script that gets the number of unread emails (another question has some code for doing that here)
