Is Mexc legal in the UK?

Could you please clarify for me whether Mexc, as a cryptocurrency exchange, is considered legal and operating within the legal framework in the United Kingdom? I'm interested in understanding if it's a reputable and regulated platform that complies with the laws and regulations set forth by the UK's Financial Conduct Authority (FCA) or any other relevant authorities. It's important for me to ensure that my investments are secure and compliant with local laws before using any such service.
