To control the visibility of a record action based on certain user conditions or expressions, the security settings of the record action itself must be configured. This involves defining conditions or expressions within the record action's security settings that evaluate whether a user meets the criteria to see and interact with the action. This method allows for dynamic control over the accessibility of actions based on user roles, specific attributes, or other contextual factors, ensuring that only authorized users can see and execute the action under specified conditions.
