What is a tab?
In Teams, tabs allow team members to access applications and content in the context of a channel inside a team. Tabs also allow team members to have conversations in the context of a tab to discuss the content the tab is displaying.
On Microsoft Teams, you will find two types of tabs: the built-in ones that come by default with the application and the custom ones that are added by applications that can be installed on Microsoft Teams, either from the store or manually uploaded.
