It's not the only instance of Ukraine using them. I didn't attempt to do a full inventory of their use. My point was they are using them when you claimed they aren't.

If you can find accurate claims of how much stock they have remaining, then sure, I very well could be wrong, but again it's curious: if they have a sizeable stockpile, why ask for more, and why the whole tone of "it'll change the trajectory of the war" and "it's necessary for Ukraine's defense" surrounding their delivery?
