Restarting a Macro

I am looking into using Kantu for a personal project.

I already see how to use if-else statements but what I can not find out is if I can restart a macro. Basically I want to go to a website. Click a button. Test if a button popped into existence or not. If the button did not pop into existence I want to continue, else I want to refresh the page then restart the script from step 2 (as if the page was just loaded).

Is this possible to do?
