We integrated some premium plugins and bundled those plugins with the theme. You don’t have to input your Themeforest product ID to unlock any theme features. We are not providing the third party plugin’s license along with the theme.
We are providing the plugins file only and we are continuously updating the bundled plugins with the theme updates. You can install/get those plugins on Appearance > Instal Plugins. Or you can get the plugin files in the saasland/inc/tgm/plugins folder.
