Decompile and change Font in an apk

I have an android apk that I would like to change the font as soon as possible.
I do not have the source code. This means I need someone to decompile, edit, then recompile.

I have attached the apk.
If you can do this, kindly, change the current font to any font of your choice then send a screenshot of the home screen to confirm that you have successfully changed the font.
