Hi
I am doing "Setting Up a Free Team Chat" lab in the start exploring section of OCI tutorial.
I come across the following and I don't know how to launch the window below with the title "edit record set"??
Can anyone help??

Before You Install Rocket.Chat
We'll need to take care of a few items before we can start the Rocket.Chat install. If you skip this step your install will certainly fail.
Domain Name Record Set
The first thing we'll need to do is associate our VM's public IP address with a domain name.
