Using the Legrand Orange Book template, I would like to get the appendix to be renumbered from A.

Currently, the \backmatter
chapters keeps the numbering from the last \mainmatter
chapter. How can I go about renumbering the Appendix chapters using Alpha Chapter deisgnators. The first Appendix chapter should show A. Appendix 1 and the section numbering should start from A.1 etc.
