Movie of teen Holidays in England

I remember seeing a movie a while back maybe around 2019. It was about a girl or a group of 3 girls traveling to England. And one of those girls got mistaken for Lady Diana. Or maybe Lady Diana disappeared and she had to pretend to be her or something. I remember that there was a scene where they were playing cricket on horse or something and she had to learn to play it😭 I watched it on a DVD but I have no idea what the name is or who was the actresses etc. Those are all the informations I got😭
