Zoom Workspace app pop-up 7-zip warning

the pop-up comes from Zoom (the icon displayed together with this warning is from Zoom Workspace) and my current version is 6.7.8 32670.  There is no local / doamin group policy blocking Zoom or 7-zip.  Some PC have 7-zip installed but some does not.  User have no admin right.  installer is MSI version.
