Use built-in and custom tabs in Microsoft Teams
Tabs allow team members to access services on a dedicated canvas within a channel or in a chat. This lets the team work directly with tools and data and have conversations about them in the context of the channel or chat.
Owners and team members can add tabs to a channel, private chat, and group chat to help integrate their cloud services. Tabs can be added to help users easily access and manage the data they need or interact with the most. This can be a Power BI report, a dashboard, or even a Microsoft Stream video channel where you publish training videos.
Work with tabs
With every new channel, two tabs are provisioned by default: Conversations and Files.
With every private chat, four tabs are provisioned by default, Conversations, Files, Organization, and Activity.
Owners and team members can add more tabs to a channel or chat by clicking Add a tab at the top of the channel or chat.
Excel, PowerPoint, Word, and PDF files must be uploaded to the Files tab before they can be converted to tabs. Alternatively, any existing uploaded file can be converted to a tab with a single click, as shown below.
To add a website, the URL must start with an https prefix so information that's exchanged remains secure.
Detailed instructions are provided when a team member tries to add a custom tab to their channel or chat. When a custom tab is added to a channel, a Tab conversation is created that allows team members to have focused discussions about the content.
Develop custom tabs
In addition to the built-in tabs, you can design and develop your own tabs to integrate to Teams or share with the rest of the community. You can control access to your custom tab by configuring the appropriate Office 365 Groups.
