Head to the **Apps** page to open the app store. We suggest adding a **calendar** integration first, then a **video conferencing** tool, and then exploring the rest.

1. Open **Apps** and find the app you want.
2. Click **Install** on the app's card to add it right away, or open the card to read the details first and install from there.

3. If the app needs authentication (for example, to connect your Google account), a dialog opens — sign in and authorize. Once complete, the app is installed to your account.
