Muzambe was invited to Spain in January 2019 with Scotland Women as 24th/25th player. After being part of the squad as 24th/25th player a few times, she gained a place on the Scotland bench in March 2019 for the 2019 Women's Six Nations Championship match against England at Twickenham, stepping onto the pitch for the final ten minutes of the game. Her second cap came when she was selected to travel to South Africa with Scotland Women in their first ever tour and their first ever matches in the Southern Hemisphere, where she had the chance to play in front of her extended family from the area.
