I'm trying to use Source Tree to push to Heroku. I've installed the Heroku CLI, so in order to clone an existing repo from Heroku, I just need to login through the terminal and it works, but if I have to push, I always get a permission denied. So I'm wondering if I need to setup something in Source Tree as I've done for my Github repo. but in settings > account... I can only pick Github or Bitbucket. So how can I authenticate and push to Heroku?
Thanks
