Fujifilm minimum operating temperatures

Is there any guidance on what temperatures Fujifilm’s should be able to operate under?

I’ve been using my X-T5 at sub -20 degrees Celsius temperatures recently. This picture was taken after roughly 30mins at -25.

I’ve noticed at around the hour mark the screen starts to smear a bit (low refresh rate?) and the battery capacity falls off.

I’ve seen some posts claiming -40 should be fine. What’s your experience with this, and are there any precautions I should take?
