[Content request]: "URL may lead to untrusted content" warning message while clicking on Action.OpenUrl action button from Adaptive Card inside Microsoft 365 Copilot chat for Declarative Agent with API plugin

[ChetanSharma-msft]

Issue type

Update to existing content

Details

If we use Adaptive Card with action as Action.OpenUrl to open the specified url and if we don't add that URL domain in app package manifest validDomain section here: https://learn.microsoft.com/en-us/microsoft-365/extensibility/schema/root?view=m365-app-1.24&tabs=syntax#validdomains

We are getting below message for a while after clicking on the button:
"URL may lead to untrusted content."

To avoid this message, we need to add the URL domain in validDomains section.

So, requesting you to please add a note in the documentation.
