Hi can anyone help on how to scrap selector for check box validation in a web interface salesforce lightning

Any reason you need to scrape the screen for checkbox?

As, If that is a checkbox you can use Checkbox Activity and then mark it as per your requirement

Regarding selector to scrape-> Try another UI framework whole selecting the screen. You can switch Between the there framework by pressing Ctrl+F4

If you are getting any error or discrepancy then you can mention that too.
