If you have Postman’s Chrome app installed, it’ll be accessible via
chrome://apps in your browser.
You can also start Postman through the Chrome App Launcher app. The Chrome App Launcher resides in your dock or taskbar. You can also keep a persistent icon for Postman that can bypass Chrome altogether.
Tip OSX users can use the Spotlight (Cmd+Space) bar and search for Postman
For Windows, the steps are the same as OS X.
In Ubuntu, you can launch Postman directly from Dash. Just search for Postman. When the icon appears in the launcher, right click and select “Lock to Launcher”
