Admin settings for apps in Microsoft Teams
The new Microsoft Teams & Skype for Business Admin Center is here! Starting in March 2018, we've been gradually migrating settings to it from both the current Skype for Business admin center and the Microsoft Teams experience in the Office 365 admin center. If a setting has been migrated, you'll see a notification and then be directed to the setting's location in the new Microsoft Teams & Skype for Business Admin Center. For more information, see Manage Teams during the transition to the new Microsoft Teams and Skype for Business Admin Center.
Apps are tabs, connectors, bots, or any combination of these three, provided by Teams (first-party apps, and also known as default apps) or by a third-party (also known as external apps). In the Microsoft 365 admin center, you can enable and disable default apps and configure settings to control external apps. These settings let you specify which external apps are allowed and disallowed, new external app behavior, and whether side-loading apps is allowed.
To manage admin settings for apps in Teams, go to the Microsoft 365 admin center and choose Settings > Services & add-ins > Microsoft Teams. If you're signed in as an Office 365 admin, this link should take you there:

Allow external apps in Teams
By default, Allow external apps in Microsoft Teams is turned on, with all apps selected. If you turn off this setting, all external third-party apps are disabled.
Enable new external apps by default
🏆 Best practice: Manage external apps individually
To turn on some apps (and turn off others), turn off Allow sideloading of external apps. Then turn off any apps you don't want your users to use. Optional: Turn off Enable new external apps by default (if you want to control new apps).
Default apps, such as those built by Microsoft, are not affected by the Enable new external apps by default setting. New apps are enabled by default when released by Microsoft.
When this setting is turned on, users can activate new apps as soon as they're added to the Teams app catalog. To open the Teams app catalog, click Store at the bottom of Teams, then click Apps. If you want to control which apps are available, turn off this setting. Of course, if you turn it off, you have to remember to review new apps periodically so your organization doesn't miss out on cool new apps.
Sideloading is how you add an app to Teams by uploading a zip file directly to a team. Sideloading lets you test an app as it's being developed. It also lets you build an app for internal use only and share it with your team without submitting it to the Teams app catalog in the Office Store.
Only team owners, or members who are granted permissions, can sideload apps into Teams.
