Creating a App promo video

Hi everyone!
I’m new and trying to create a promo video for my App. I’ve found many template here (thanks Envato!) but can’t find information about portrait template
For example, I found this template: G3 - App Promo by DREAMYARD_Visuals on Envato Elements but I don’t know if it has portrait resolution or only landscape?
I’m trying to create facebook ads video

Thanks for reading my question!
