Type 'AbstractControl' is not assignable to type 'string' / Unable to cast and save individual information from formGroup

Hey everybody. I have a form group for the information of a transaction and I want to get the individual field values of the form to save it.
When I check the logs it shows that the data from the form is being fetched without problems:

amount: "420444"
destination: "DE36584fh9"
recipient: "John Johnso545n"
reference: "Testerinoadfhg"

however, I want to be able to access the individual values of the form instead of the whole form as an object because I have a function that takes several arguments so what I want to do is to have individual values for
amount, destination, etc.

this is my form:

this.transactionForm = formBuilder.group({
      recipient: [''],
      destination: [''],
      amount: [0.01],
      type: ['now'],
      reference:  [''],
      date: [new Date().toISOString().split('T')[0]]
    });

and this is what I tried to do to save the information:

this.templateServicerino.createTemplate(this.transactionForm.controls['destination'], this.transactionForm.controls['recipient'], this.transactionForm.controls['amount'], this.transactionForm.controls['reference'] );

when that didn’t work I tried a single value just to check:

let referencerino: string;
referencerino = this.transactionForm.controls['reference'];

and the IDE shows the error : TS2322: Type ‘AbstractControl’ is not assignable to type ‘string’.

Thank you in advance for your help

I just found that the solution was not to use formGroup.controls but formGroup.value

referencerino = this.transactionForm.value['reference'];

this solved it
