How to centre payment methods and submit button on mobile view?

[Beamaway]

Hi there, 

How can I centre my footer text on mobile view, I've implemented a section from the app "Section Store" which is perfect for my desktop format however the footer submit button and payment methods aren't centred. How would I go about centring it? Thanks
