Howto to use a ansible-galaxy role in a task

Hi,

I have a ansible playbook which setups the configuration of my work computer (which uses fedora).

I discovered https://galaxy.ansible.com/eddyhub/gnome_shell/ which allows me to install gnome extensions. But I am unsure of how to integrate this in my existing playbook.

I would like to create a task in a role of the playbook that installs the gnome extensions. So how do I call a role from ansible-galaxy from within a task?

Thanks!
