This command registers the Flathub repository with Flatpak, allowing you to access a wide range of applications, including Postman.

Step 3: Install Postman

Now you can install Postman from Flathub by running:

flatpak install flathub com.getpostman.Postman

Follow the prompts to complete the installation. This process might take a few minutes, depending on your internet speed.

Step 4: Launch Postman

After the installation is complete, launch Postman using the following command:

flatpak run com.getpostman.Postman

Alternatively, you can find Postman in your applications menu and launch it from there. To make it easier to access, you can create a desktop shortcut or add it to your favorites.
