Unable to find "artifactory" in the list of "service connections" in Azure Devops

I am new to Azure Devops and integration of Azure Devops with Artifactory. I am following up the documentation and trying to add a service connection to Artifactory, from my free account of Azure Devops.

But I cannot find "Artifactory" in the list of service connections, as mentioned in the documentation. Can somebody please help me how to create a service connection to Artifactory?

Below is the list of service connections which I see in my Azure Devops :

In Azure Devops, you need to install the extension: JFrog Artifactory.

Then you could get the Artifactory Service Connections

Here is a doc about installing the Extension in Azure Devops (Search JFrog Artifactory).
