Customize design in mobile

Hi, community,

I can’t find a way to customize this design in mobile. Whenever we invite someone and this person opens it on the phone this screen is shown. I want to use corporative colors, change the order of the text and add some logos and images. How can I do it?

Thank you in advance

Thank you; but I can’t find the file DeepLinkingMobilePage.web.js
I found app.bundle.min.js but of course, it’s kind of hard to work with it

You need to work with the source code, app.bundle is the compiled source.
