Changing event links on index page

Hi there,

I’m trying to change the event details link to point to the eventbrite.com url rather than the single post page on my site. Reading the developer documents I see that there is a filter eventbrite_event_eb_url which I understand should update the url as per my requirement.

I’ve implemented the filter in my functions.php file but the output remains the same. What have I missed?

function filter_event_url($html) {
	return "abcd";
}

add_filter('eventbrite_event_eb_url', 'filter_event_url', 10, 0);

Appreciate any help
