You can use a factory function here to pass the page, and the global_variable. Keep in mind that navigating away from the page from inside the callable will lead to an error. So make sure whatever you are clicking does not change the current URL of the page.

def wrapper(page, global_variable):
    def test(event):
        page.locator('//*[@id="n-currentevents"]/a').click()  # Action before boolean
        if event.url == 'https://en.wikipedia.org/':
            return True
    return test

Then, you can register the above function using page.wait_for_event like this:

page.wait_for_event('request', wrapper(page, global_variable))

Remember: You need to pass functions/callables (not their return values) to page.wait_for_event
