How to uninstall ExpressVPN?

[dimpetrov2018]

Hi there. I recently had to update my iphone (iphone X if that matters) and since i was away from home i installed ExpressVPN and i let it configure my iphone. It gave me 7 days trial and it only asked for my email, it didn't even gave me option to create password. I dont know why is that, but i suggested it would probably allow me after the trial. Any way i want to get rid of it for now because i will be heading home and i dont need vpn right now. From what i read in the internet all i need to do is sign out and delete the app. I freind told me that that wont do and i need to somehome manually uninstall the configuration it created? But i never so any option like that. Also in the express vpn official page says that if i want to remove it i simply have to delete it from my iphone? Is that enough or i should do more. Thanks.
