In the Postman app, if the right click isn’t working, you can click on the ellipsis (…) next to the collection name, and select “Publish Docs” to take you to the documentation view in the web.
As @bhargavkaranam96 said from the web dashboard, you’ll need to select workspace > select collection > green button in the top right that says Published dropdown > Edit Published Documentation will take you to the screenshot that he showed. Unpublish is the red button at the top. Including a screenshot for orientation.
