+3. create a new app from scratch and link to the workspace created at step #1
+4. Open *OAuth & Permission* section
+5. Add new redirection URL: *<domain>/auth/slack.callback* (e.g. *https://outline.giovanesaggio.com/auth/slack.callback*), then save
+6. Open *Basic information* section and copy the two secret codes in the .env file.
