What is Aquis Exchange plc?

Could you please elaborate on what Aquis Exchange plc actually is? I'm curious to understand the role it plays in the world of cryptocurrency and finance. Is it a trading platform, a broker, or something else entirely? How does it differ from other exchanges out there? I'd also be interested in knowing if it's a publicly traded company and what kind of services or products it offers to its clients. Thank you in advance for shedding some light on this topic.
