Still a room for video conferencing platform?

I use Teams, Zoom and Google meets as main tools for calling someone. They are excellent for conversation and discussion, but I'm thinking about something more interactive, something that allows participants to engage with the host. Both Teams and Zoom provide apps that can be used in a call. I think Teams integration is more seamless because Zoom asks users to download on both ends, and Zoom is not usable in browser.

I teach English to niece and nephew every Sunday but I'm surprised that the only I can engage them is via a different app. I have to send them a link and access code. They open a link, type the code and can start playing. It still works but it should more seamless, more integrated, isn't it?

I just wonder if there is any video conferencing platform that works like Houseparty (calling with many fun interactive activities) but more for education?
