How to SCHEDULE Zoom Workplace updates

[S-Painter]

The average age of our user community is well over 65. Almost none are technical. Almost all are change adverse. Many members still have trouble making Zoom work after 3 years of using it. It is VERY IMPORTANT that we schedule client upgrades after 4/23.

How can I do this? 

Is there a way to configure our meetings so that Zoom Workplace looks similar to the current UI?  Any way to control what buttons are shown to the users (the array of buttons at the bottom of the current UI confuses some users).  

Thanks,

Steve
