Hi Hasib,
You can use Verify_Element command and make use of the Attempts and Intervals fields.
For example, if we want to use the loading spinner element as a locator for this command, we can disable the checkbox "Exist" and this command will keep looking to make sure this element does not exist on the page. Attempt #1 will start the initial check, wait for Interval (10,30,40 seconds) and then perform another check on attempt #2, and so on. Once the spinner has disappeared, the step should pass shortly after.
