I have a wait command via API with opened browser and browser closed before condition is set true. How to increase timeout If no new command reaches and what is it?
loginPage.login();
await fetch.startSimulate(id);
await fetch.waitJobCompleted(id, "SIMULATE"); //while it is in progress browser unexpectedly closed
header.openNotifications();
