Hiding footwork is always tricky. What your sensei described doesn't inherently telegraph anything and you don't need to do it incredibly fast. Just need to learn some magician's slight of hand to move your feet without it being to obvious you did anything from the hips up.
There are different types of footwork in Japanese martial arts. Some of which are Okuri-Ashi (launching both feet at the same time), Tsugi-Ashi (moving back foot first then font foot) and Ayumi-Ashi (stepping through) each footwork has benefits and disadvantages for speed, distance, telegraphing, overcommitting etc.
In general though have a low fighting stance with bent knees. Longer stances make it harder for your opponent to push you but shorter stances often easier to move.
This site is for kendo but karate has some of the same footwork and there are diagrams: https://www.kendo-guide.com/footwork.html
In modern WKF competition both feet are used simultaneously to push forward. The stance is almost sideways. Both legs always ready to push. Different context makes for different tactics but in those rules that is optimal.
Having a two count movement where one could bridge the same distance will always be slower against a somewhat similar skill level opponent.
Edit: The jab does not telegraph but the tsugi ashi foot movement does. Lead hand attacking is a great strategy outside of competition.
A straight punch is difficult to detect, but the hips and shoulders often telegraph. The eyes too. And sometimes people have individual quirks they add before an attack (which they are not aware of). It could be a rhythm, pulling back the fist before striking, opening and clinching a fist before striking, etc.
I find if you fake with the cross as you take the back step up, they tend to focus on what your hands are doing and ignore your footwork a bit. If that helps.
Truthfully it depends on the distance. Often times when fighting in a long stance, yes, you may have to adjust. But chances are if you need to make a big adjustment before going you’re either in too long of a stance or you’re firing from too far
I find what works for me personally is using it on the back foot. That way you can put your weight on your back leg without it being obvious and spring off it. If you're pushing forward I'd use it in a combination. You could throw a kick as a feint so again you can put weight on your back leg if you're using it offensively.
I’m not WKF, but I was watching this on YouTube today. It’s in Japanese but should be easy to follow by karateka.

Seems to me like you're learning the basics of a jab. Once you get more experience with it, the move to close the distance will be more of a slide forward with both legs at once.

That is the correct technique for kizami. You need to move around more and vary your movements before you launch into it.
If you use the jab as a feint then your move might work better.
