The code is missing rapid approach to hole bottom. Obviously the post is missing something. What's the preferred way fix to this?

I looked at NCI and the toolpath just emits G0 and G1 codes, and it is also missing the G0 to the hole bottom at each peck. There seems to be no way of knowing when you're pecking (is there a flag?), so you can't add the missing G0 move before the G1 code. Also I noticed that 2022 has "rapid to bottom" option, so I was right in my guess and advanced drill peck in 2021 seems to be broken.

<rant>Why won't they just stick to UI and leave the toolpaths to ModuleWorks, because even the simple ones are obviously too hard to get right?</rant>

Advanced Drill was new in 2021. It has been improved for 2022. Yes, you should use the checkbox to force a rapid move down to the last drill peck depth, and then it will feed to the next depth, and repeat. 

Say what you will, but we had to do this for the last 15 years by building Custom Drill Cycles, which wouldn't even show any of the pecks, or any other start/end moves, so this is a huge improvement. 2021 needed some improvements, which they have made, and I'm sure there is still room for additional improvements in the next couple of versions.

Advanced Drill has been a huge addition. Especially for users who don't use pecks because we've got Coolant Thru-Spindle to flush the chips. Now I can approach a hole with the drill spinning  CCW at 500 RPM, feed to the start depth slowly, stop the spindle, turn on the spindle CW at the start RPM, ramp the RPM up in stages while enabling the CTS pressure to build, then drill my hole to depth. Finally I get control over the retraction process steps as well.

Yeah, maybe I was a bit too harsh with words, but the first impression I got when I realized there is no way to rapid down was "whoever designed this has no idea what pecking means". Luckily they realized the error and it was fixed quickly in the next release.
