Go for a jibe yes, not a tack.
As some has said, carve (turn) around downwind and practice riding toeside on the new tack, and then carve back again to your original direction, good practice and somewhat how you do when you ride waves "Down The Line" as it is called, when you ride S turns up and down the waveface, along the wave wind a bit from the side.
Good practice you will need anyways.
It will come pretty quick.
Now you can try to make a jibe where you switch your feet also, and can ride away on the new tack normally.
Carve around to toeside, not too much speed (important), and keep the kite a bit high so it helps you.
Quickly move your rear foot (foot closest to the tail) up to the front foot, and your front foot back - in a fast two step move, and thats it
This is by far the most important skill to learn, so start with above.
Can be used when jibing in both windsurfing and kitewaveboards and hydrofoiling, so an important skill you can use "everywhere" so to speak.
Works no matter if you ride strapless or with straps, no difference in this jibe, so an important skill that can be transferred to everything
When you get better you can make it as a jump with both feet at the same time if you want, but start out doing a fast two step feet shuffle, also safer so many of us keep doing this on waveboards.
Later you can start to switch feet earlier, on the way out of the turn, so you are planing on the way out, but require a lot more timing.
You can also switch feet before the turn, but would not advice this till later, if you want to learn this too.
Have fun, a new world is opening now
