Exercises/courses with Knight tactics and forks for 1600 ELO

Hi, everyone!

I'm searching for my daughter some exercises/courses with Knight tactics and forks and haven't found anything. I am specifically looking for something with Knights because she's having trouble with them. 

I have also tried to extract some for her - I downloaded the Lichess puzzle database and tried to create (with the help of ChatGPT) a script that searches through the database and only gives back those exercises, but it's not working properly. Also, I have tried to match PyChess with Stockfish and create some from scratch, but that also failed. 

Any ideas? Thank you!

Hello. I'm a beginner, so I don't know much, but there's an app called Hungry Horses that maybe could help her.
