Add a connection

/**
* Fetch a model from cache with specified connection.
* @param int|string $id
* @param class-string $class
* @param string|null $connection
*/
public function findFromCache($id, string $class, ?string $connection = null): ?Model

The issue only identifies findFromCache($id, string $class, ?string $connection = null) and its intended connection parameter; no source file or test is named. Start by locating this method and its cache behavior, then determine the expected connection-specific behavior and add coverage showing the change is complete.
