There are so many ways to do this. It all depends on what you want to do, if you want to pay for it, etc. Thanks to COVID-19, a lot of businesses and even civic groups have been looking at this. I had to find something for our Boy Scout troop to keep in touch. I ended up using Google Hangouts, mainly because the free version of Zoom limits you to 45 minutes. If you're only doing one-on-one video chats, there are even more options for you. Apple phones use FaceTime, Google (android) has Duo, and you can even use FaceBook messenger to video chat. As BionicJohn mentioned, all parties have to use the same application.
