Kernel configuration in Ubuntu

I’m trying to get my own flavour to work with annotations.
I’m building Jammy master-next in a u22 chroot.
I’ve made changes to the kernel source to add my flavour. New files. Updated files. Kconfig changes, etc.
In debian.myflav/config/annotations, I have:

# Menu: HEADER
# FORMAT: 4
# ARCH: amd64
# FLAVOUR: amd64-generic
# FLAVOUR_DEP: {'amd64-myflav': 'amd64-generic'}

include "../../debian.master/config/annotations"

And I should put all the CONFIG_ things I want, in it as well, correct?

CONFIG_MYNEW                                      policy<{'amd64': 'y'}>
CONFIG_OLD                                        policy<{'amd64': 'n'}>
CONFIG_ETC                                        policy<{'amd64': 'y'}>

Do I need to copy the rest of the debian.master directory into debian.myflav?

And, building like this will work?

fakeroot debian/rules -j5 binary-myflav

And, I don’t need anything else?
