Currently, Teams doesn't support device permissions for multi-window apps, tabs, and the meeting side panel. We have updated the documentation to reflect this. Ref Doc: Native device permissions

not having polls requests generated

Could you please elaborate more on this part?

Are you looking to track how many users sent "Hi" and were able to get the response back from Bot and how much time did that take for response?

@AbhishekNegi-1282 - Website tabs aren't equivalent to a standard web browser. A number of sites, especially those requiring authentication, using popups, or complex HTML framing, will not work as expected when pinned as a website tab. Recommended option to load SharePoint tags is by creating Teams App as mentioned by @Meghana-MSFT .

Removing office-teams-app-dev tag as this not related to Teams App Development related query.

@AmirSohail-0150 - Currently we do not have Graph APIs to fetch the meeting transcription file. We are working on this but do not have an ETA to share.

Could you please confirm if custom app uploading setting is turned on?

Are you still facing this issue? Here is documentation on Manage app policies in Microsoft Teams

@Saiyam-7598 - are you seeing this only for Microsoft Teams specific APIs?

@Stefan-3800 - could you please confirm what specific on Update the Teams configuration step?

@SahiRepswal-9632- Could you please confirm if your bot endpoint is recieving invoke request? You can Test and debug your bot locally using ngrok.

Please share the code snippet for your hero card along with the function which is handling the invoke request.

DanielRivers-7702 - could you please share the request and response along with response headers? Please remove the access token/ any other personal information.

Could you please change your code to WithAuthority($"{Instance}/{Tenant}")?

@Huzaifa-9671 - To get the correct token for Microsoft Teams Free and guest users, it is important that the apps use tenant specific endpoint https://login.microsoftonline.com/{tenantId}. If the apps use https://login.microsoftonline.com/common, the users will get incorrect tokens and will log on to the "home" tenant instead of the tenant that they are currently signed into.
Easiest way to get your tenant Id by logging in to https://teams.microsoft.com/ using your personal account.

Graph Explorer by default logins to home tenant. Could you please try following the steps mentioned in get access token documentation and let me know if it works for you?

@SharmaMeghnaGECoreTechCyber-7678 - For notification from custom apps, you can use sendActivityNotification APIs.
