What is the consequence of granting tab visibility to a group without view permissions on the object?

When granting tab visibility to a group that does not have view permissions on the corresponding object, the tab will be effectively hidden from the group members. This happens because, in order to access the data associated with the tab, users must possess view permissions on the object. If those permissions are absent, even if the tab itself is visible, users won’t be able to interact with or see its contents, leading to the assumption that the tab is hidden for them.

This mechanism ultimately ensures that data security and object-level permissions are maintained within the organization, reinforcing that users only see the components they are permitted to access. Thus, while the tab visibility itself may allow for visibility settings, the lack of object permissions supersedes this, rendering the tab irrelevant to those users.
