How to implement ngx-spinner in an Angular http subscribe operation

I'm trying to incorporate a spinner into my Angular Application using ngx-spinner. I've come across this library but haven't found enough practical examples on how to use it effectively. Specifically, I want to integrate the spinner with my http requests. Can someone guide me on how to properly show and hide the spinner in this context?

public getCars(){
 this.spinner.show();
  this.appService.getCars().subscribe(
    car => {
      this.carList=car;
      for (let i = 0; i < this.carList.length; i++) {
        let make = this.carList[i].make;
      }
      this.spinner.hide();
    },
  );
}

I have successfully installed and imported ngx-spinner, however, I am facing challenges in utilizing it within my http requests. Any assistance or suggestions would be greatly appreciated.

In my opinion, the correct placement for "this.spinner.hide();" is directly under the closing brace of the "for" statement. This signifies the success-callback in the code.

          for (let i = 0; i < this.carList.length; i++) {
            let brand = this.carList[i].brand;
          }
          this.loading.hide();
        },
      );
