1. Even if the activity is executed as the first one, the robot waits before its execution. By default, for 200 milliseconds, but in this case, the value in DelayBefore is set for 10 seconds.
2. If the corresponding selector cannot be found on the screen, the robot waits by default for 30 seconds for it to appear. If the corresponding selector cannot be found during those 30 seconds, an error is thrown. If ContinueOnError is set to True, then the error is ignored and the error message does not appear.
3. After executing the activity, the robot waits before executing the following activity. By default, for 300 milliseconds, but in this case, the value in DelayAfter is set for 1 minute. However, as the corresponding selector is not found, an error is thrown and the robot does not wait for DelayAfter, even if ContinueOnError is set to True.
