The super admin can set the visibility of companies in a partner space:

1. Contacts of different external companies in a partner space are invisible to each other in the partner space Contacts.
2. They cannot see or chat with each other in the partner space either.
3. Company admins and partner space owners can allow companies to view or chat with contacts of other companies in a partner space based on business needs or for security purposes:

   Go to “Workspace” -> “Partner Space” in the WeCom app.
   Tap the “Switch” button in the upper-right corner to enter the partner space for setting modification.
   Go to “Contacts” and tap “Set View Permission” -> “Set visibility between external companies” to set whether to “Allow external companies to view each other”.
   Once it is enabled, companies in the partner space can view and chat with contacts of other external.
