Changing zoom settings via registry

Hi All

Does anyone know how i can use windows registry to change zoom settings for corporate accounts? We need to force all of our zoom users to have zoom start up with windows. I found a mass deploy article but the details in there dont seem to work. 

Anyone know what registry key/dword etc i would need to create to have this enforced? I'm then looking at pushing out the registry key via GPO to enforce it on all client machines.

Cheers
