If you really need to install the app you can always try sideloading by grabbing a copy over at APK Mirror, and for the time being, the Hangouts web interface is still live.

The Chromebooks that many students have handy are now able to install the Chrome extension for Zoom, Hangouts Meet, and more.

Google Hangouts is the tech giant's app for free video and voice calls as well as group messaging. You need a Google account to start a call, but you can join one without it.

Zoom, Google Hangouts, Microsoft Teams and Skype are all free, though Teams and Zoom have paid versions too. You can be sillier on non Zoom apps.
