Use Microsoft Graph to post to the activity feed
Hi, Trying to add the option for my custom app to send notification to the teams activity feed using Microsoft graph. (The app already has tab and connector). https://docs.microsoft.com/en-gb/learn/modules/msteams-teamwork-endpoint/6-activity-feed First question would be, is it possible to send activity feed notification to anyone that has installed my app even if he is not from my organisation, or is it only limited for users in the same active directory. The documentation is not very clear about it. The second question is regarding the flow that happens when someone is installing the app. "resource": "api://app.contoso.com/8a2d385d-8504-43f8-a9b2-80caa44bfe22" What happens in this callback above , is it just a communication between azure AD and the MsTeams? Not much is mentioned regarding it. Also how would the app's server be informed that someone has installed the app and get the teams id? Is this information being shared at the above callback, or do we need to pull Microsoft graph and check for users and teams Id's that installed the custom app? Any help will be appreciated.
