Disconnect

To disconnect from MsGraph call a ->disconnect() method.

The disconnect will send a POST request to MsGraph to revoke the connection, in addition, the stored token will be deleted.

MsGraph::disconnect();

Typically you only want to run this is there is a connection, so it makes sense to wrap this in a ->isConnected() check:

if (MsGraph::isConnected()) {
    MsGraph::disconnect();
}
