I don't think we ever will. Only two of the first batch of Short Treks were even on the Discovery Blu-ray, and they only went to Netflix at the last minute, right before season two aired.Star Trek release dates are annoying:
1. when will the rest of the world be able to see the remaining Short Trek Episodes? Children of Mars is supposed to be a prologue to ST PIC, yet non u.s. citizens will most likely not be able see it (legally) before the show starts. Weird!
With the current Short Treks split between Pike, Discovery and Picard, it must be a minefield for Amazon and Netflix.
