Meeting fellow travelers or locals in Moscow

Hii I almost will start my solo trip to Russia. Currently traveling solo in Belarus as a 22-years old Dutch traveler. Here it is quite difficult to get in contact with other people. I was wondering if anyone has suggestions on how to meet fellow travelers or locals in Moscow to explore the city with or go out for a coffee or a drink? (I speak Russian as well, would say level between B1 - B2)
