# Joining as a contact

This section details how to join a VR collaboration session on Android when you have been invited as a contact by the host/administrator. This assumes you already have a SimLab account registered with the email address the invitation was sent to.

#### Joining via In-App Notification (SimLab VR Viewer)

If you are signed into the SimLab VR Viewer, the application will provide real-time notifications about scheduled sessions you are invited to.

**Prerequisites:**

- SimLab AR/VR Viewer is installed and running on your system.
- You are **Signed In** to the SimLab AR/VR Viewer application.

**Action (In-App Join):**

1. **Notification Prompts:** The Viewer will display timed messages leading up to the scheduled start time:
    
    
    - *Example:* At 4:45 PM for a 5:00 PM session, you will receive a notification stating you have 15 minutes before the session starts. A similar prompt will appear at the 5-minute mark.
2. **Host Initiates Session:** When the host/administrator clicks **Start Collaboration** within their SimLab VR Viewer, you will receive the final launch prompt in the Viewer.
    
    
    - *Message:* "\[Host Name\] has invited you to join a Collaborative VR Experience session."
3. **Tap the 'Join' Button:** Tap the **Join** button within the notification window to immediately launch and enter the collaborative VR session lobby.
