Hubspot Zoom Integration

Hi

I can’t find Webinar ID to add to Hubspot workflow. We opened a webinar using Events. Which ID I should add to the workflow to have it add a user to Zoom event on form submission?

Also - how do pull data from Zoom event into Hubspot? Hubspot asking for a user, but the user currently connected is not relevant any longer. Should I uninstall and reinstall?
