This method, available in tags detector handlers, allows for the search of a specific tag within the received predictions. It can be used in a non-blocking manner by setting up a callback that will be triggered when the desired tag is found, or it can be used in a blocking mode, where the method will return the prediction when the desired tag is found. If callback_async is defined, the callback is ignored. If wait is False, one of the callbacks must be defined.
