Is there a way to add a service (such as the 'Teams' Service) in roblox Studio?

hello.the following question has nothing to do with scripting! it's just a problem with the servers that happened on my map. So i was creating a race map and i decided to create some checkpoints. The problem is that when I went to Roblox Studio's 'Teams' service, he just wasn't there, he disappeared.

There is a simple way to get this back in again, either do it in a script: game:GetService("Teams") or by going to the "Model" tab, then "Service" and find the teams service
