How to turn off video on Spotify?

This is a lot different from most questions on here but does anyone know how to turn off the video for the podcast on Spotify? I’m back at school and have to listen to the podcast without WiFi (long story) and it’s absolutely destroying my cel data because of the video. I just want to listen to the pod, I don’t understand why I have to watch them sit around and talk along with it

Do you not download the pod when you’re on wifi so as to avoid data charges? I would assume it downloads the video too, but I’m actually not sure…
