c++ : how to discover any subscribed topics and topics properties name and type

hi
according to documentation, we can find any data writer that able to publish a topic. this ability is possible by subscribing to the "PublicationBuiltinTopicData" topic.
into the "PublicationBuiltinTopicData" topic just we can find topic_name and now we need to find the discovered topic properties name and properties type.
is there any way to access from topic_name to topic_variables?
