Should I invest in engagement platforms for my live events like online webinars, training?

Hi! We're planning to host virtual events like live streaming, watch parties, and online webinars in hopes of further reaching out to our target audience and we read about this engagement platform on this site https://viafoura.com/virtual-events-engagement/ that could complement virtual events really well by helping us spark engagement from all attendees. I noticed that some of the biggest publishers and media brands make use of these kind of platforms so I'd like to ask if it's a good idea to invest in one.
