Create an unlimited invite list using Workform

I want to use a monday.com workform to create an invite list. I want to send the form to each of our employees to add as many invitees (name, company, title, email) as they want and I want these invitees to be fed directly into a board. So far I can only make a form making space for one invitee. I understand there might be a “repeating sections” option that would allow the employee to click a plus or something to add another invitee – we want to allow for unlimited invitees. How do I do this. If there is a repeating sections option, where do I find that? I cannot see anything that looks like that.
