Hi Patrick,
One way you might be able to do this is with the shortcodes that come with Events Calendar Pro, which let you specify a date from which events should show, including dates in the past. Otherwise, I am not familiar enough with Elementor to offer any other suggestions (also please note that we are not able to provide technical support here in the Pre-Sales forum), and integrations are outside the scope of support that we are able to provide (even in our premium forums).
We do offer full refunds within 30 days of purchase, so if you’d like to take Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
