firestore update a map field

Issue

Hello I have the following code, and I want to replace the long ID with my variable but I am not sure how can I insert the variable in between. I want it to be 'cursos.curso.calificaion': calificacion, were curso is the variable. Thank you

examAttempt(user: any, curso: any, calificacion: any) {
this.afs.doc(`users/${user.id}`).update({
  'cursos.tkGXjZLxRdg1TcXGGCD0.calificaion': calificacion,
  'cursos.tkGXjZLxRdg1TcXGGCD0.intentos': 5
});

}

Solution

What I did is save the route of how to fin d on firebase in a string variable and just pasted the variable.
