  ngrok http 3978 --host-header="localhost:3978"

  Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

Getting the App id for share to stage deeplink.

1. Navigate to Teams admin portal

2. Under Teams Apps section, select Manage apps.

3. Search the uploaded app and copy the App ID

4. Navigate to samples/meetings-stage-view/csharp/AppInMeeting/ClientApp/src/components/app-in-meeting.jsx

5. On line 41, replace <<App id>> with Id obtained in step 3.

6. Navigate to samples/meetings-stage-view/csharp/AppInMeeting/ClientApp/src/components/share-to-meeting.jsx

7. On line 24, replace <Application-Base-URL> with your application's base url whrre app is running. E.g. if you are using ngrok it would be something like https://1234.ngrok-free.app and if you are using dev tunnels, your URL will be like: https://12345.devtunnels.ms.

8. On line 25, replace <<Application-ID>> with Id obtained in step 3.

9. When the app is running, the home page will contain a share to teams button. Clicking it will share the page content directly to meeting. (Make sure the app's base url is added in manifest's valid domains section and app is published to store).

5. Setup Manifest for Teams

• This step is specific to Teams.

  • Edit the manifest.json contained in the ./AppManifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
  • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
  • Zip up the contents of the AppManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

• Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

  • Go to Microsoft Teams. From the lower left corner, select Apps
  • From the lower left corner, choose Upload a custom App
  • Go to your project directory, the ./AppManifest folder, select the zip folder, and choose Open.
  • Select Add in the pop-up dialog box. Your app is uploaded to Teams.
