You can do that with the “Child Theme Configurator” plugin.
so, first, install and activate the plugin, then go to: Tools->Child Themes
1. In Child theme configurator menu select “CREATE a new Child Theme”
2. Select AgamaPro theme from the theme drop-down list

Finally, click on the “Create new child theme” button to create the child theme.
If everything is OK. you will get this message on top of the screen.
“Child Theme Agama Pro-Child has been generated successfully. IMPORTANT: Preview your child theme before activating.”

Then you can activate your child theme.
