Unable to use Clipboard API in custom Teams App

New Contributor



Im trying to develop a teams app, and an integral part of the app is to be able to copy a string to the clipboad of the user.


The app works fine when viewed in the browser (not as an embedded page within the teams enviroment), but while using it in teams the following error appears: 

Microsoft.JSInterop.JSException: The Clipboard API has been blocked because of a permissions policy applied to the current document. 
See https://permanently-removed.invalid for more details.

So is there any way to update the clipboard permission policy within our organization?

I really can't seem to find any documentation regarding the Clipboard policy for teams / 365.



The app is built with Blazor and TeamsFx sdk.
