Looks like Postman extension is not supported on Chrome anymore.
I tried to run it by clicking on the icon in chrome://extensions/ page.
I searched in net and found this article
I removed the Postman extension and downloaded Postman-linux-x64-7.14.0.tar.gz
file, but I stuck at how to install it to follow the instruction?
Thanks!
sudo apt install snap
snap install postman
Try two above commands in the terminal.
