Apps let you do more in Microsoft Teams. They can show up in several places, depending on what they do and how they’ve been built.
Apps in tabs
Apps can be used in channels or chats.
Select the plus sign next to the tabs.
Select the type of app you want or Search.
Apps in messages
Select More options under the message box, choose an app, and select Add.
Apps as Connectors
Are there certain notifications that are useful to the whole channel? Go to the channel you want, select More options > Connectors, and choose an app. Then you’ll be prompted to configure notifications.
Looking for all apps? Select Apps on the left-hand side, and browse for the app available to your organization. Some require subscriptions or signing-in.
