Hi @MJs88,
As long as the tablet meets the minimum system requirement for the Zoom mobile app, you should be able to install and use Zoom on it: https://support.zoom.us/hc/en-us/articles/201179966-System-requirements-for-iOS-iPadOS-and-Android
Android Go has access to all Google Play Store apps, so you should find Zoom there.
Just keep in mind that Android Go is for lower-end devices (like the Lenovo Tab M7) so performance with the Zoom mobile app may be sluggish at times. A lot of the default apps on Android Go run on web technologies in order to run on lower-end devices, so traditional Android apps (like Zoom) may not run smoothly on them.
Hope that helps!
