How to iterate over FormArray in FormGroup in an Angular reactive Form

The Structure of my form is as shown below

-MainForm(ParentForm)
 -FormGroup(MedicineGroup)
  -FormArray(MedicineArray)

I wanted to iterate MedicineArray for which, i did some research and wrote the below code

for (let control of soForm.get('MedicineGroup').controls['MedicineArray'].controls) {
    medObj.name.push(control.controls['MedName'].value);
  }

The code is working fine but i am getting a warning, which says

Property 'controls' does not exist on type 'AbstractControl'.

Is there any other or better way to iterate a FormArray which is inside a FormGroup?
