Which workspace role can view all content but cannot take any actions like quick actions or mass actions?

The correct choice is the Limited Member role. This role is designed to provide users with the ability to view all content within a workspace but restricts them from taking any actions, such as executing quick actions or performing mass actions. This means that while Limited Members can observe and analyze the data or posts available to them, they do not have the permissions necessary to modify, interact with, or manage the content. This role is particularly useful in situations where organizations want to ensure that certain team members have insight into the workspace without granting them control over its content or functionality, thereby maintaining oversight and security.

In contrast, other roles such as Contributor, Workspace Admin, and Workspace Owner typically have greater permissions that allow them to engage with the content directly, take actions, and manage various aspects of the workspace. Thus, they do not align with the description of a role that can solely view content without taking actions.
