    In a social networking platform's friend recommendation system, given a user's connection status represented as a binary number where each bit indicates an active (1) or inactive (0) connection type, write a function that activates the highest-priority inactive connection type by setting the leftmost unset bit. The connection types are arranged in descending order of priority from left to right, and the function should identify and activate the first available inactive connection type to enhance the recommendation accuracy.
