How about a small handle bar bag :) Like burrito / tubular shaped?
We like the stem / snack bags:

I’ve got two of the Velo orange cages, love them. I use them when Bikepacking, while logging around miles around town I use feed bags. The cheapo Amazon one is good: https://www.amazon.com/Moosetreks-Handlebar-Bikepacking-Commuting-Insulated/dp/B076MPQSZD
The Revelate Designs one is better though: https://www.rei.com/product/115540/revelate-designs-mountain-feedbag-handlebar-bag
$20 dollars better, to me, yeah, but I’m a picky bitch. My buddies love their moose tracks ones.
I have had my eye on this one for a while but I haven’t purchased it yet.
