How to claim ONG?

Excuse me, could you please elaborate on the process of claiming ONG? I understand it's associated with Ontology blockchain, but I'm not quite clear on the specific steps required to acquire it. Is there a specific wallet or platform I need to use? Also, are there any prerequisites or conditions that I must fulfill in order to be eligible for claiming ONG? Additionally, could you provide any insights into the potential benefits or use cases of ONG within the Ontology ecosystem? I'm eager to learn more and appreciate your assistance.
