The airplane in question is a Pipistrel Alpha Electro, which has been around since 2015.
I note it has "up to 60 minutes" under "endurance".
What I believe is the non-electric version of the plane is here: https://www.pipistrel.si/plane/alpha-trainer/overview
That has an endurance of 3.1 hours with its standard 50-liter fuel tanks.
