Adding 'Chapter 1' instead of '1' and 'Appendix A' instead of 'A' to the Contents page in in Masters/Doctoral Thesis template

Question

I have downloaded the latex template for doctoral thesis available in https://www.latextemplates.com/template/masters-doctoral-thesis. In the content page, the chapters and appendices appears as:

1. Introduction

2. Methods...

A (Appendix title)

B (Appendix title)

But instead I would like to have them as follows:

Chapter 1. Intrduction

Chapter 2. Methods

Appendix A

Appendix B

Is there anyway to do that?
