Hello MS,
I am working through the Tutorial on this page:
https://docs.microsoft.com/en-us/microsoftteams/platform/get-started/first-app-bot?tabs=vscode
I am in the section "Run your app locally" and am on this step "From Visual Studio Code, press F5 to run your application in debug mode".
I run the code in Debug mode but get a different response to that stated in the insructions. First Visual Code opens a Teams instance in Chrome which is odd as Safari is my default browser. And secondly I get this error "Permissions needed. Ask your IT admin to add helloWorld-local-debug to this team/chat/meeting" (See attached screen shot). But none of the expected prompts, not any buttons such as "Approve App". 
Can you advice on how to proceed?
Thanks.
