        <h2>Shared Cursor example</h2>
        This example shows how to connect two <a href="https://get.cct.ericsson.net/latest/docs/reference/Client.html"></a> together through a <a href="https://get.cct.ericsson.net/latest/docs/reference/Room.html">room</a>. Once they both have joined the room, a peer-2-peer WebRTC <a href="https://get.cct.ericsson.net/latest/docs/reference/Room.html#startCall__anchor">call</a> is set up. Once the call is set up a <a href="https://get.cct.ericsson.net/latest/docs/reference/DataShare.html">DataShare</a> is created between the two clients sending their respective cursor data to eachother.
