Divergence indicator alterations (add alerts to the indicator only) URGENT

I need a divergence indicator indicating all divergence (regular & hidden) in tradingview. I have some indicators that are great but they do not have any alerts in them or even tell me how to use the alerts. I also do not know if we can copy-paste then modify their scripts or there is some kind of law against it but I just need to add an alert on them so I can get notifications.
