await driver.waitUntil(async ()=>{
    // Get All Context
    const contexts = await driver.getContexts();
    return contexts.length > 1;
}, 
// Timeout with message if context not found after 30 seconds
{timeout: 30000, timeoutMsg: 'Timeout waiting for context'});

await driver.switchContext(contexts[1])
