The 'Postman' icon is not displayed
Solution 1:
You might want to edit the desktop entry file at /usr/share/applications/postman.desktop
Example postman.desktop file:
[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=postman
Icon=/opt/Postman/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;
Also, I learned that they had updated the icon path in the latest releases. So, you can just go ahead and change the path of icon at .desktop file.
